End Products of Photosynthesis
 
07:18
Join us on Facebook: https://www.facebook.com/Schoomin Plants prepare their own food and so they are called as Autotrophs. They synthesize food from sunlight through a process called Photosynthesis, in the presence of sunlight and Chlorophyll, resulting in the formation of water, oxygen and glucose as end products. This video demonstrates some experiments through which the presence of all the end products can be sensed.

What Is Photosynthesis? | Biology for All | FuseSchool
 
03:25
We wouldn’t have life without photosynthesis; life processes depend upon it. Not only are photosynthetic organisms the main producers of food, but without photosynthesis Earth’s atmosphere would lose its oxygen. In photosynthesis is that green plants and algae trap light from the sun to fix carbon dioxide with hydrogen and water. This makes organic compounds which then provide food for not only the plant itself but also all animals. Photosynthesis happens in leaf cells. They contain tiny organelles called chloroplasts, which contain a green substance called chlorophyll. Chlorophyll molecules sit on the surface of the chloroplasts and capture light energy from the sun, which is fundamental for photosynthesis. Photosynthesis is a chemical reaction, in which carbon dioxide and water are converted to glucose and oxygen, by the energy provided from the light energy absorbed by the chlorophyll. It is an endothermic reaction because it takes in energy from surroundings. carbon dioxide + water ( + light energy ) → glucose + water. The light energy is not a substance, but it is an essential requirement for photosynthesis to happen. So we know the light energy comes from the sun, and is absorbed by the chlorophyll. But where do the carbon dioxide and water come from? Plants absorb water through their roots, and it moves through the plant and into the leaves by transpiration. Watch our video on ‘Xylem and transpiration’ to learn more about this process. Carbon dioxide enters into leaves from the air, through the stoma on the underside of the leaf. What then happens to the glucose and oxygen that are made? Some of the glucose is used for respiration and some is converted into insoluble starch. This can then be stored and turned back into glucose to be used at a later date. Oxygen is actually just a by-product of photosynthesis. There are some useful by-products in this world. Green plants are called producers or autotrophs, because they have the ability to produce their own food. They are the start off the food chain, and every animal relies upon them either directly if they are a herbivore or indirectly if they are a carnivore.

You can eas­i­ly re­peat it at home and amaze your friends and fam­i­ly. Reagents and equip­ment: * so­lu­tion of bak­ing soda (5 g/l); * wa­ter plant (in our case it is wa­ter­weed); * beaker; * fun­nel; * test tube; * match or splin­ter; * lamp. Step-by-step in­struc­tions Place the wa­ter plant in the beaker, cov­er it with a fun­nel and fill the beaker with the salt so­lu­tion, then place a test tube con­tain­ing wa­ter in the fun­nel. Turn on a bright light and wait for around two to three hours. Af­ter the test tube fills com­plete­ly, care­ful­ly re­move it from the fun­nel and hold a smol­der­ing splin­ter or match up to it. Watch the splin­ter burn. Pro­cess­es de­scrip­tion Pho­to­syn­the­sis is a com­plex chem­i­cal process in which light en­er­gy trans­forms into the en­er­gy of chem­i­cal bonds, or more sim­ply it is a process in which car­bon diox­ide and wa­ter trans­form into or­gan­ic sub­stances and oxy­gen un­der the im­pact of light: СО₂ + Н₂О → Or­gan­ic sub­stances + О₂ It is easy to prove the pres­ence of oxy­gen – just low­er a smol­der­ing splin­ter or match into the test tube, and it will im­me­di­ate­ly flare up, as oxy­gen is a gas that sup­ports com­bus­tion. Why the so­lu­tion of bak­ing soda is re­quired: as the car­bon diox­ide in the air dis­solves poor­ly in wa­ter, to in­crease its con­cen­tra­tion we can use car­bon­ates or bi­car­bon­ates, which by their na­ture are salts of car­bon­ic acid (CO₂・H₂O).

Subscribe to watch more online chemistry courses & science videos: http://www.youtube.com/channel/UCiX8pAYWBppIbtUZTfGnRJw?sub_confirmation=1 About Atomic School: Atomic School supports the teaching of Atomic Theory to primary school & science students. We provide lesson plans, hands-on classroom resources, demonstration equipment, quizzes and a Teacher's Manual to primary school teachers. Animated videos that clearly explain the scientific ideas supports learning by both teachers and students. As a teacher, you don't have to look anywhere else to implement this program. Our work has been verified by science education researchers at the University of Southern Queensland, Dr Jenny Donovan and Dr Carole Haeusler, who confirm that primary students are capable of learning much more complex scientific concepts than previously thought, and crucially, that they love it. Students run to class! The program has been trialed in Australian schools as well as schools in the Philippines, Iran and India. It is conducted as holiday workshops at the Australian Nuclear Science and Technology Organisation, the Queensland Museum as well as the World Science Festival. It has attracted wide media interest, including TV, radio and print, and the research data has been presented at prestigious American Education Research Association and Australian Science Education Research Association conferences. Atomic Theory underlies all the other sciences- genetics, electronics, nanotechnology, engineering and astronomy- so an early understanding will set them up for a more successful learning sequence for all their science subjects, and support their mastery of mathematics as well. We also have extension programs that cover Biology, Physics and Astronomy to an equal depth. About Ian Stuart (Email: [email protected]): The founder of Atomic School, Ian Stuart, taught Chemistry and Physics for 25 years at senior levels before he realized that his 8-year old son, Tom, could understand Atomic Theory at a much deeper level than he expected. After visiting Tom's class at school, he discovered that his peers could also grasp the abstract scientific concepts, as well as apply it usefully to the real world. Ian then developed a program to teach the advanced concepts of high school Chemistry, Physics and Biology to students 10 years younger than they normally would. He found that this engaged their interest in modern science early, and sustained it through to high school and beyond. It also sets them up for future success in their academic and career paths. Ian has a Bachelor's Degree in Chemistry from the University of Queensland and a Master's degree in Electrochemistry from the University of Melbourne.

Plants also pull water molecules up from the soil. Plus you may have noticed that plants need sunlight in order to survive. Sunlight is a form of energy. So what do plants do with this combination of carbon dioxide, water and energy? With the help of the energy, they reassemble the molecules into a new molecule called glucose. Hang on, we're just met glucose in our respiration reaction, but instead of burning it as a reactant, plants make it as a product. Not only that, whereas we breathe in oxygen, plants breathe out oxygen. So oxygen is another product of this reaction. The chemical reaction that allows plants to use sunlight to enable plants to turn carbon dioxide and water into glucose and oxygen is called photosynthesis. It's the exact opposite of respiration. Let's do our steps to balance our photosynthesis equation. Step 1: Write the reactant and product names. Remember, carbon dioxide was breathed in from the air, and water was taken from the soil, so they're reactants. Glucose and oxygen were made, so they're products. The word "breathed" is a bit misleading here, because plants don't have lungs. Instead, the carbon dioxide and oxygen molecules exit and enter through the plant leaves, through little holes called "stomata", which are the plant equivalent of noses. Step 2: Convert those names into formulas. Carbon dioxide is CO2, water his H2O, glucose is C6H12O6 and oxygen is O2.

What is Photosynthesis ?
 
01:10
Photosynthesis is a process by which plants make their own food. "Photo" is a greek word which means Light and "synthesis" means to put together. So, photosynthesis means "using light to put together". Plants need 3 things for Photosynthesis: 1) Water - Taken-in by the roots from the soil. 2) Carbon-di-oxide - Leaves absorb it from the air. 3) Sunlight - The green pigments of leaf, Chlorophyll trap sunlight to start this process. End product of photosynthesis is GLUCOSE, a simple sugar which is distributed throughout the plant as Food.

Check us out at http://www.tutorvista.com/content/biology/biology-ii/nutrition/photosynthesis.php Define Photosynthesis Photosynthesis is a process that converts carbon dioxide into organic compounds, especially sugars, using the energy from sunlight. Photosynthesis occurs in plants, algae, and many species of bacteria, but not in archaea. Photosynthetic organisms are called photoautotrophs, since they can create their own food. In plants, algae and cyanobacteria photosynthesis uses carbon dioxide and water, releasing oxygen as a waste product. Photosynthesis is vital for life on Earth. As well as maintaining the normal level of oxygen in the atmosphere, nearly all life either depends on it directly as a source of energy, or indirectly as the ultimate source of the energy in their food(the exceptions are chemoautotrophs that live in rocks or around deep sea hydrothermal vents). The amount of energy trapped by photosynthesis is immense, approximately 100 terawatts: which is about six times larger than the power consumption of human civilization.As well as energy, photosynthesis is also the source of the carbon in all the organic compounds within organisms' bodies. In all, photosynthetic organisms convert around 100,000,000,000 tonnes of carbon into biomass per year. Although photosynthesis can happen in different ways in different species, some features are always the same. For example, the process always begins when energy from light is absorbed by proteins called photosynthetic reaction centers that contain chlorophylls. In plants, these proteins are held inside organelles called chloroplasts, while in bacteria they are embedded in the plasma membrane. Some of the light energy gathered by chlorophylls is stored in the form of adenosine triphosphate (ATP). The rest of the energy is used to remove electrons from a substance such as water. These electrons are then used in the reactions that turn carbon dioxide into organic compounds. In plants, algae and cyanobacteria, this is done by a sequence of reactions called the Calvin cycle, but different sets of reactions are found in some bacteria, such as the reverse Krebs cycle in Chlorobium. Many photosynthetic organisms have adaptations that concentrate or store carbon dioxide. This helps reduce a wasteful process called photorespiration that can consume part of the sugar produced during photosynthesis. Overview of cycle between autotrophs and heterotrophs. Photosynthesis is the main means by which plants, algae and many bacteria produce organic compounds and oxygen from carbon dioxide and water (green arrow). Photosynthesis evolved early in the evolutionary history of life, when all forms of life on Earth were microorganisms and the atmosphere had much more carbon dioxide. The first photosynthetic organisms probably evolved about 3,500 million years ago, and used hydrogen or hydrogen sulfide as sources of electrons, rather than water. Cyanobacteria appeared later, around 3,000 million years ago, and drasticaly changed the Earth when they began to oxygenate the atmosphere, beginning about 2,400 million years ago This new atmosphere allowed the evolution of complex life such as protists. Eventually, no later than a billion years ago, one of these protists formed a symbiotic relationship with a cyanobacterium, producing the ancestor of many plants and algae. The chloroplasts in modern plants are the descendants of these ancient symbiotic cyanobacteria.

Erika Tan explains the process of photosynthesis at the molecular level. *** If there are any pictures used in this video, they are NOT MINE and I will not take credit for them. *** TRANSCRIPT: Before we take a look at photosynthesis as the process itself, you should get used to the structure of the chloroplast first. Here’s a diagram of the chloroplast and all of its labeled parts. So you can see that there’s a double membrane; this one is the inner membrane and that one’s the outer membrane. The intermembrane space is the area between the two membranes. Then there are these sacs inside of the chloroplast. They’re called thylakoids, and one column of these thylakoids makes up a singular granum. All of these grana are surrounded by a fluid called the stroma, which is kind of like the matrix of the mitochondrion if you’ve seen my cellular respiration video. And of course, there’s chlorophyll and other photosynthetic pigments that give the plant its color in the thylakoid membranes. Here’s an action spectrum of the pigment called chlorophyll a, and we can see that it mostly absorbs the red and blue-ish violet colors, but not the green. That’s because it’s reflecting the green waves, so that’s why we see that many plants are, in fact, green. There are two steps of photosynthesis: the light reactions, also called photophosphorylation, and the Calvin cycle. Let’s talk about the two types of photophosphorylation now: noncyclic and cyclic. During noncyclic photophosphorylation, water is split in order to donate electrons and protons to the electron transport chain. When two water molecules are split, it gives off O2 as a byproduct since oxygen is a diatomic molecule, meaning it’s naturally found consisting of two atoms. Alright, so we know that water is split, but what happens next? Well, there are two photosystems involved in the process that harvest light and power the reactions. Photosystem II starts it off by absorbing light wavelengths of 680 nanometers (nm), exciting the electrons in the complex. Then, a primary acceptor accepts these electrons, powering the electron transport chain that happens between photosystems II and I. By the way, even though photosystem II functions first, they were named as they are by the order of discovery, so photosystem I was found first although it functions second. Anyways, during the electron transport chain, a proton gradient is created in the thylakoid membrane so that H+ protons are pumped from the stroma into the interior of the thylakoid. As the proton supply in the thylakoid interior builds up, the H+ will diffuse down the gradient through an ATP synthase complex and power the making of ATP. Remember, this is called photophosphorylation because the phosphorylation of ADP to ATP is powered by light. You can also describe this process using the word “chemiosmosis” because the protons are diffusing down a gradient in order to power a reaction. So now, more light energy is absorbed by photosystem I, which absorbs wavelengths of 700 nm. Another acceptor accepts the excited electrons, and a molecule called NADP+ picks up the two H+ protons from the water molecule that was split before, turning into NADPH. We say that NADP+ has been reduced to NADPH, since it’s gaining electrons and is therefore getting more negative, reducing its charge. Okay, so the light reactions make NADPH and ATP. Let’s move on to the Calvin cycle. But let me just get one thing straight with you before we start: you do NOT need to know all of the specific steps for the AP exam, thankfully. I’m just going to give you the important information that you do need to know. So first of all, CO2 enters the stroma of the chloroplast where the cycle actually takes place. This first step is called carbon fixation, which is catalyzed by an enzyme called rubisco. A molecule of CO2 is attached to a five-carbon sugar called RuBP, or ribulose biphosphate. Now the sugar is a six-carbon molecule, which immediately breaks down into two three-carbon molecules. Through reduction and a series of chemical reactions powered by ATP and NADPH, a molecule called G3P or PGAL is formed. This is the three-carbon sugar produced from the Calvin cycle, and it is NOT glucose. Glucose is a product that can be FORMED from G3P molecules. It’s important to notice that NADPH and ATP power the reduction of PGA into G3P, resulting in NADP+ and ADP. We can see that both the light reactions and the Calvin cycle therefore depend on each other because the products of one process powers the other. So if one shut down, the other would, too. Finally, other G3P molecules regenerate RuBP, allowing the cycle to continue again.

What is Photosynthesis?
 
02:03
Hi, I'm Emerald Robinson, and in this "What Is" video, we're going to discuss one of biology's most important processes: photosynthesis. Photosynthesis is the process by which green plants (and some bacteria) change light energy and carbon dioxide gas into usable chemical energy in the form of a sugar called glucose. The overall biochemical reaction for photosynthesis is: Carbon dioxide plus water yields glucose and oxygen gas. Light energy (usually from the sun) and a special green pigment molecule called chlorophyll are needed to complete this reaction. The process of photosynthesis has two parts: the light cycle, and the "Calvin" cycle. When light strikes a chlorophyll molecule, it excites some of its electrons, and causes them to leave the molecule. Light also splits a water molecule into hydrogen and oxygen. The oxygen is a waste product, and leaves the plant as oxygen gas. But the electrons and hydrogen create two energy-carrying molecules, ATP and NADPH. Therefore, the light reaction changes light energy into chemical energy, which is necessary for the next part of photosynthesis. In the Calvin cycle, the ATP and NADPH produced in the light reaction are used to "fix" carbon dioxide into sugar. "Fixing" means plants take the carbon dioxide gas, which can't be used by animals, and change it into glucose, which they can use. Why is photosynthesis so important? The ability to capture the energy of sunlight to make glucose puts plants at the bottom of the food chain, making them the primary producers of the energy needed for much of life on earth.  Even the waste product of photosynthesis, oxygen, is necessary for animals to survive.  Hundreds of millions of years ago, the earth's atmosphere was mostly carbon dioxide. Thanks to photosynthesis, there's now enough oxygen to sustain animal life.

In so doing, photosynthesis provides the basic energy source for virtually all organisms. An extremely important byproduct of photosynthesis is oxygen, on which most organisms depend. Leaves are specialized organs on the stems of plants. Their most important function is to carry out the process of photosynthesis. All the necessary raw materials for photosynthesis come together in the leaf. Water comes from the plants' roots and carbon dioxide in the air enters through stomata, pores, in the leaf. Chlorophyll, the green pigment in leaves, captures light energy. The products of photosynthesis are oxygen and carbohydrates. In the leaf the excess glucose is changed to starch. If photosynthesis is taking place in the leaf, the leaf will contain starch. This video explains how to show experimentally that light is necessary for photosynthesis.

Photosynthesis - Calvin Cycle
 
06:40
The Calvin Cycle or the Light independent reactions of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside of the thylakoid membranes. These reactions take the products (ATP and NADPH) of light-dependent reactions and perform further chemical processes on them. There are three phases to the light-independent reactions, collectively called the Calvin cycle: carbon fixation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration. The Calvin cycle, Calvin–Benson–Bassham (CBB) cycle, reductive pentose phosphate cycle or C3 cycle is a series of biochemical redox reactions that take place in the stroma of chloroplast in photosynthetic organisms. The cycle was discovered by Melvin Calvin, James Bassham, and Andrew Benson at the University of California, Berkeley[3] by using the radioactive isotope carbon-14. Photosynthesis occurs in two stages in a cell. In the first stage, light-dependent reactions capture the energy of light and use it to make the energy-storage and transport molecules ATP and NADPH. The Calvin cycle uses the energy from short-lived electronically excited carriers to convert carbon dioxide and water into organic compounds[4] that can be used by the organism (and by animals that feed on it). This set of reactions is also called carbon fixation. The key enzyme of the cycle is called RuBisCO. In the following biochemical equations, the chemical species (phosphates and carboxylic acids) exist in equilibria among their various ionized states as governed by the pH.

What happens in the light reactions of photosynthesis?
 
05:21
light strikes photosystem 2, exciting the electrons. The electron come from a water molecule that has been split into hydrogen and oxygen. That is the first reactant (water), and Oxygen gas is given off as the first product. The excited electrons then travel down a short electron transport chain, and while doing so they pump H+ molecules (hydrogen molecules) into the inner thylakoid space across the thylakoid membrane from the stroma. The electrons are then passed, at the end of the transport chain, to photosystem 1, where they are re-excited by light. The electrons are passed down another short electron transport chain, which pumps a few more H+ into the thylakoid space, then the electrons get passed to a molecule of NADP+, which is reduced to NADPH. NADPH is a product, NADP+ a reactant. The H+ in the thylakoid then diffuse back into the stroma through a molecule of ATP Synthase that is a channel through the memebrane of the thylakoid. As they pass through the ATP synthase, the H+ make the ATP Synthase go into it's active conformation so it is able to turn ADP into ATP. ADP is a reactant, ATP is a product. To sum it all up, H20, NADP+, and ADP are reactants, and oxygen, NADPH, and ATP are products

Photosynthesis: The Light Independent Stage in a Snap! Unlock the full A-level Biology course at http://bit.ly/2VZhmTq created by Adam Tildesley, Biology expert at SnapRevise and graduate of Cambridge University. The key points covered of this video include: 1. Overview of the Light Independent Stage 2. Fixation of Carbon Dioxide 3. Formation of Organic Molecules in the Calvin Cycle 4. The Regeneration of RuBP Overview of the Light Independent Stage The light independent stage is the second stage of photosynthesis and it occurs in the stroma of chloroplasts. In the light independent stage the products of the light independent stage and carbon dioxide are used to synthesize organic molecules. The main metabolic pathway of the light independent stage is called the Calvin Cycle. Although the Calvin Cycle does not require light energy, it does depend on the products of the light dependent stage. Therefore if there is no light, the products of the light dependent stage do not form and thus the Calvin Cycle cannot take place. The pumping of the protons into thylakoid space during the light dependent stage increases the pH of the stroma to 8. A pH of 8 is the optimum pH for the enzymes involved in the Calvin Cycle. Fixation of Carbon Dioxide in the Calvin Cycle Carbon dioxide from the atmosphere diffuses into the leaf via the stomata. This carbon dioxide then diffuses across the plant cell wall and chloroplast envelope and into the stroma. The first step of the Calvin cycle involves carbon dioxide combining with the 5 carbon compound ribulose biphosphate (RuBP). This reaction is catalysed by the enzyme RuBisCo (ribulose biphosphate carboxylase-oxygenase). This reaction causes the RuBP to be carboxylated which forms an unstable intermediate compound with six carbons. This unstable six carbon compound immediately breaks down to form two molecules of glycerate-3-phosphate (GP). This whole process is referred to as the fixation of carbon dioxide. Formation of Organic Molecules in the Calvin Cycle After carbon dioxide has been fixed, GP is reduced to form the organic molecule triose phosphate (TP). GP is reduced to TP using hydrogen atoms from the reduced NADP that was formed in the light dependent reaction. The ATP that was made in the light dependent reaction is then also used at this stage to make two molecules of ADP. Therefore for each molecule of carbon dioxide, two molecules of ADP are produced. From the Calvin Cycle, two molecules of TP are needed to synthesize the hexose sugare glucose. This glucose can then be converted to sucrose, starch or cellulose for use in the plant cell. TP can also be used to synthesize amino acids, fatty acids and glycerol. The Regeneration of RuBP Chloroplasts contain only low levels of RuBP because it is continuously being converted to GP. In order for the Calvin cycle to continue, RuBP has to be regenerated. Therefore 10 TP molecules out of every 12 TP molecules are used to regenerate six molecules of RuBP. The remaining 2 molecules out of 12 molecules of TP are the product and these are used to synthesize organic compounds like glucose. Summary The light independent stage of photosynthesis takes place in the stroma of the chloroplasts The main metabolic pathway in the light independent stage is the Calvin cycle Although the Calvin cycle does not directly need light energy, it is reliant on the products of the light dependent stage therefore it cannot occur without light The Calvin cycle involves the fixation of carbon dioxide where carbon dioxide is combined with RuBP to form GP GP is then reduced using the hydrogen atoms from reduced NADP formed in the light dependent reaction and this process produces the organic molecule TP TP can then be used to synthesise more complex organic molecules like glucose, amino acids, fatty acids and glycerol RuBP has to be regenerated so 10 TPs out of every 12 TP molecules are used to regenerate RuBP The remaining 2 TP molecules out of the 12 are the product and are used to synthesise complex organic molecules

The process of photosynthesis occurs when green plants use the energy of light to convert carbon dioxide (CO2) and water (H2O) into carbohydrates.

An extremely important by-product of photosynthesis is oxygen, on which most organisms depend. Glucose, a carbohydrate processed during photosynthesis, is mostly used by plants as an energy source to build leaves, flowers, fruits, and seeds. Molecules of glucose later combine with each other to form more complex carbohydrates such as starch and cellulose. The cellulose is the structural material used in plant cell walls. Photosynthesis provides the basic energy source for virtually all organisms. This video explains how to show experimentally that light is necessary for photosynthesis.

Photosynthesis
 
08:18
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities (energy transformation). This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis. In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies all of the organic compounds and most of the energy necessary for life on Earth. In plants, algae and cyanobacteria, long-term energy storage in the form of sugars is produced by a subsequent sequence of light-independent reactions called the Calvin cycle; some bacteria use different mechanisms, such as the reverse Krebs cycle, to achieve the same end. In the Calvin cycle, atmospheric carbon dioxide is incorporated into already existing organic carbon compounds, such as ribulose bisphosphate (RuBP).Using the ATP and NADPH produced by the light-dependent reactions, the resulting compounds are then reduced and removed to form further carbohydrates, such as glucose. Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide. Site of Photosynthesis is in Chloroplasts.

This animation provides a brief overview of how a plant uses the products of photosynthesis for biosynthesis. It is appropriate for high school through college-level students and even middle school students with appropriate scaffolding. The molecules generated by photosynthesis provide energy and matter that allow producers to grow and ultimately fuel the food chain. A product of photosynthesis is a three-carbon sugar called G3P. This sugar can be used to make other carbohydrates such as sucrose, which is transported to stems, roots, and other parts of the plant. For long-term energy storage, plants use G3P to form starch. Organic molecules formed from G3P are also used for the biosynthesis of other organic compounds.

Chemical reactions in Photosynthesis
 
02:04
Chemical reactions in Photosynthesis Photosynthesis is an important process that happens every day and night. It happens in plants and bacteria and it produces glucose from carbon dioxide and water using the energy from sunlight. It has a by-product important for life here on Earth, this by product is called oxygen. Photosynthesis has many chemical reactions within it and these reactions play important roles in everyday life. #rxneverywhere We made this video by researching the following sources: https://www.khanacademy.org/science/biology/photosynthesis-in-plants/the-light-dependent-reactions-of-photosynthesis/a/light-dependent-reactions

Photosynthesis - How Does Photosynthesis Happen? | Learn with BYJU'S

Photosynthesis is one of the most crucial, if not the most crucial process in the plant kingdom. What is Photosynthesis? It is the process by which plants convert energy from the sun, that is light energy into chemical energy, and stored as carbohydrate molecules. The Photosynthesis process in further detail is how carbon dioxide and water react to form sugar and oxygen as the by-product. This reaction is responsible for releasing oxygen as a waste product, which is the oxygen that sustains the balance between animal life and plant life on earth. Hence, justifying the importance of the photosynthesis reaction. The carbon dioxide required for the process is taken in through the stomatal pores, whereas the water and other minerals required are taken in through the plant's roots. The photosynthesis reaction occurs at the leaves where the sunlight is incident on the plant. Now inside a plant cell, we have the chloroplast which is suspended in the cytoplasm. This Chloroplast contains the chlorophyll, which is responsible for the magic that happens. The chlorophyll converts the carbon dioxide and water into the sugar molecule and gives out oxygen as a waste product. This sugar molecule which is technically food for the plant is what releases energy for the plant's activities. The heavy abundance of Chlorophyll present is what is responsible for the green color of plants. The Chlorophyll absorbs red and blue colors of light and reflects out the green colored light, hence the green color.

Photosynthesis - Light Dependent Reactions
 
06:19
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities (energy transformation). This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis. In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies all of the organic compounds and most of the energy necessary for life on Earth. In plants, algae and cyanobacteria, long-term energy storage in the form of sugars is produced by a subsequent sequence of light-independent reactions called the Calvin cycle; some bacteria use different mechanisms, such as the reverse Krebs cycle, to achieve the same end. In the Calvin cycle, atmospheric carbon dioxide is incorporated into already existing organic carbon compounds, such as ribulose bisphosphate (RuBP).Using the ATP and NADPH produced by the light-dependent reactions, the resulting compounds are then reduced and removed to form further carbohydrates, such as glucose. Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide. Site of Photosynthesis is in Chloroplasts.

Photosynthesis Dark reaction /C3 cycle
 
11:22
The light-independent reactions, or dark reactions,[1] of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside of the thylakoid membranes. These reactions take the products (ATP and NADPH) of light-dependent reactions and perform further chemical processes on them. There are three phases to the light-independent reactions, collectively called the Calvin cycle: carbon fixation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration. This process occurs only when light is available. Plants do not carry out the Calvin cycle during nighttime. They instead release sucrose into the phloem from their starch reserves. This process happens when light is available independent of the kind of photosynthesis (C3 carbon fixation, C4 carbon fixation, and Crassulacean acid metabolism); CAM plants store malic acid in their vacuoles every night and release it by day to make this process work. They are also known as dark reactions. In the first stage of the Calvin cycle, a CO2 molecule is incorporated into one of two three-carbon molecules (glyceraldehyde 3-phosphate or G3P), where it uses up two molecules of ATP and two molecules of NADPH, which had been produced in the light-dependent stage. The three steps involved are: 1. The enzyme RuBisCO catalyses the carboxylation of ribulose-1,5-bisphosphate, RuBP, a 5-carbon compound, by carbon dioxide (a total of 6 carbons) in a two-step reaction.[5] The product of the first step is enediol-enzyme complex that can capture CO 2 or O 2. Thus, enediol-enzyme complex is the real carboxylase/oxygenase. The CO 2 that is captured by enediol in second step produces a six-carbon intermediate initially that immediately splits in half, forming two molecules of 3-phosphoglycerate, or 3-PGA, a 3-carbon compound[6] (also: 3-phosphoglyceric acid, PGA, 3PGA). 2. The enzyme phosphoglycerate kinase catalyses the phosphorylation of 3-PGA by ATP (which was produced in the light-dependent stage). 1,3-Bisphosphoglycerate (1,3BPGA, glycerate-1,3-bisphosphate) and ADP are the products. (However, note that two 3-PGAs are produced for every CO 2 that enters the cycle, so this step utilizes two ATP per CO 2 fixed.) 3. The enzyme glyceraldehyde 3-phosphate dehydrogenase catalyses the reductionof 1,3BPGA by NADPH (which is another product of the light-dependent stage). Glyceraldehyde 3-phosphate (also called G3P, GP, TP, PGAL, GAP) is produced, and the NADPH itself is oxidized and becomes NADP+. Again, two NADPH are utilized per CO 2 fixed. also see; https://youtu.be/Kc2w5eO571E cellular respiration ; https://youtu.be/4_X3CanX6iE
