How do the reaction help the Calvin cycle?
Light reactions produce NADPH and ATP, which are used during the Calvin cycle.
What is the relationship between the light dependent reaction and Calvin cycle?
The two reactions of photosynthesis are connected by two substances: ATP and NADPH. These are produced by the light dependent reaction and are used by the light independent reaction. ATP is produced from ADP and Pi (phosphate): ADP + Pi ---> ATP This reaction requires energy to make it work, and this energy comes from light absorbed in the light dependent reaction. NADPH is produced from NADP+ and H: NADP+ + H ---> NADPH This reaction also requires energy, which is obtained from light in the light dependent reaction. The ATP and the NADPH are used in the light dependent reaction to provide energy and a source of H to convert CO2 to CH2O (carbohydrate). The products of the reactions (ADP, Pi, NADP+) are recycled in the light dependent reaction to produce more ATP and NADPH.

What is the function of a stroma in a leaf?
The stroma of a plant is the region outside of the thylakoid space. This serves two functions in the both the light-dependent and light-independent (Calvin cycle) reactions. In the light-dependent reactions, the H+ ions that build up within the thylakoid begin to form a concentration gradient between the thylakoid and the stroma. As a result, the H+ ions need to diffuse into the stroma. In order to do this, the ions must travel through an enzyme known as ATP synthase. Once it does, the movement of H+ ions through ATP synthase into the stroma provides energy for ADP to become ATP. The ATP formed is an energy source to power the Calvin cycle. Now, the light-independent (Calvin cycle) reactions occur in the stroma. in short: Its function is for production of ATP.
What is produced from the splitting water during the light-dependent reactions What is this process called?
During the light dependent reaction, it produced Oxygen and Hydrogen..hope that can help...:D
What three thing do plants need to carry out photosynthesis?
Water, (sun)light and carbon dioxide are three things that plants need to carry out photosynthesis. The water is used to replenish the lost electrons of chlorophyll and provide protons for the chemical gradient. The light is used as the source of energy to initiate photosynthesis. The carbon dioxide is the source of carbon to help make the complex sugar (made in the Calvin cycle).
How do the reaction help the Calvin cycle?
Light reactions produce NADPH and ATP, which are used during the Calvin cycle.
How do the light reaction help the Calvin cycle?
they provide energy carriers
Summarize what happens during the Calvin cycle?
Is used to creat NADPH+ to carry energy to other parts of the chloroplast Is used to create some ATP from ADP Is udes to breakup water into protons, electrons, and oxygen atoms (with help from enzymes) Hope that helped (:
Why doesn't Calvin cycle occur at night?
Obviously, there is no sunlight energy for light dependent reactions to occur while calvin cycle AKA light independent phase does not require light as it uses energy in the form of ATP and the NADPH to form sugars

What are the reactants and products of light-dependent reaction?
kk so first u must understand tht the Light reaction and the calvin cycle r totally differentthe light reaction aka the light dependent reaction depends on light, this reaction takes place in the stroma, in the chloroplast. U can research more about how it exactly works but basically the products of it is ATP and NADPH2. These products u get them after the light from the sun goes through cyclic or non cyclic reaction. ADP + Pi = ATP and NADPH+ + H+ = NADPH2Then photosynthesis continues, the next step is carbon fixation. Carbon fixation is still part of the light dependent reaction. After the carbon gets fixed it enters the Calvin cycle.the calvin cycle is now part of the dark reaction aka the light independent reactions, and like the name says it does not depend on light energy. The calvin cycle takes place in the thylakoid, which is in the chloroplast.Here is goes through a series of steps in which enzymes to different stuff to it to get the CO2 into an organic molecule..The main enzyme is called Rubisco (which is a short form for Ribulose biphosphate carboxylase/oxygenase). the calvin cycle produces glucose, but u need 6 turns of the calvin cycle for every molecule of glucose. the calvin cycle also produces carbohydrates, like lipids.Glucose is energy for the body, it can be broken down to get ATP, by a process called glycolysisfurthermore, there are other things tht happen in between these steps tht help photosynthesis continue, such as hydrolysis and chemiosmosis to produce more ATP through a concentration gradient and ATP synthataze. u must take into account tht these processes are very complex and the description above is only a brief overview, im not sure wut grade ur in n how much u need to kno. so with the names of it u can look it up
Why does a plant produce sugar?
The plant produces sugar during the Calvin Cycle of photosynthesis. This is part of the "dark reactions" in the stroma, which reduce CO2 to C6H12O6, or glucose (simple carbohydrate). The Calvin Cycle is also known as the "Sugar Factory" of the plant.
What happens during light independent stage of photosynthesis?
In the light-dependent stage, plant cells absorb light energy through proteins containing pigments, such as chlorophyll. In the final part of the stage, the process called photophosphorylation turns ADP into ATP, using the light energy taken in to make these high-energy molecules. ATP and NADPH are used in the Calvin cycle, which is called a "light-independent" stage, to remove carbon from carbon dioxide to use in creating glucose and other molecules.

What is the importance of light in photosynthesis?
The equation of photosynthesis is as below:Carbon dioxide + Water ---------> Glucose + OxygenThis reaction takes place in the presence of light and chlorophyll.The process of photosynthesis is completed in two stages:-Light Reactions: When light falls on leaves, it is absorbed by the chlorophyll in the chloroplasts. The solar energy is utilized to split water into oxygen and hydrogen, this process is called photolysis, and oxygen is released during this process. As these reactions take place only in the presence light, they are called light reactions.During light reactions two compounds are formed when solar energy is converted into chemical energy, these are:NADPH (Nicotinamide Adenine Di-nucleotide Phosphate)ATP (Adenosine Tri-Phosphate)NADP already exists in the cells of the leaf. The hydrogen released on the photolysis of water molecule is accepted by this compound and it becomes reduced to form NADPH.NADP (in cell) + H (from water) ---------> NADPHThis reaction takes place in the presence of light and enzymes.The compound ADP (Adenosine Di-Phosphate) is already present in the cells of the leaf and combines with the phosphate group using light energy to form a compound called ATP.ADP + P ---------> ATPThis reaction also takes place in the presence of light and enzymes.These compounds are energy rich and are needed for the dark reactions in photosynthesis.Dark Reactions: Utilizing the energy from ATP and the hydrogen from NADPH, water combines with carbon dioxide to form carbohydrates. Thus, the solar energy is now converted into chemical energy to form glucose. Other organic compounds are further synthesized from this glucose.This stage is also completed in a series of chemical reactions with the help of enzymes . Scientists have discovered an interesting thing about these two stages: only the first requires light, and the second can occur in the dark. So we call these reactions light and dark reactions respectively. Neither light energy nor chlorophyll are required for the dark reactions.Various steps of the dark reactions were studied by a scientist named Melvin Calvin, thus dark reactions are also known as Calvin's Cycle. When scientists performed experiments with chlorella plant, they found the rate of photosynthesis increased in non-continuous supply of light and again if the temperature is raised during dark reactions, the rate increases invariably. This also proved that light reactions are photochemical reactions which involve light, and dark reactions are chemical reaction which do not involve light.
What occurs during the second stage of phytosynthesis Help like now please?
During the second stage of photosynthesis, also called the Calvin Cycle, CO2 is used to turn organic molecules into sugar.
