Why are NADH and ATP needed for the Calvin cycle?

Reduction. In the second stage, ATP and NADPH are used to convert the 3-PGA molecules into molecules of a three-carbon sugar, glyceraldehyde-3-phosphate (G3P). This stage gets its name because NADPH donates electrons to, or reduces, a three-carbon intermediate to make G3P.

What is the function of NADPH in the Calvin cycle?

NADPH is an energy-carrying molecule produced in the first stage of photosynthesis. It provides energy to fuel the Calvin cycle in the second stage of photosynthesis.

What are the roles of ATP and NADPH in photosynthesis?

ATP and NADPH are energy storage and electron carrier/donor molecule. Both ATP and NADPH are used in the next stage of photosynthesis. The chlorophyll molecule regains the lost electron from a water molecule through a process called photolysis, which releases dioxygen (O2) molecule.

Where do the ATP and NADPH go when the process is complete?

Where do the ATP and NADPH produced during the light-dependent reactions go when the process is complete? The NADPH and ATP are made in the stroma. These molecules will be used in the Calvin Cycle to make glucose.

What is the function of NADPH and ATP *?

So in summary, there are two main roles of NADPH and ATP: (1) they tie the light dependent reactions and the light independent reactions together and (2) they act as sources of energy to take the energy from the sun to the light independent reactions to make the plants food.

What is the role of NADPH and ATP in the light independent reactions?

The light-independent reactions of photosynthesis take place within the stroma. It contains enzymes that work with ATP and NADPH to “fix” carbon from carbon dioxide into molecules that can be used to build glucose.

How are ATP and NADPH made in the light reactions?

(In the light reactions, the energy of sunlight is used to oxidize water (the electron donor) to O2 and pass these electrons to NADP+, producing NADPH. Some light energy is used to convert ADP to ATP. The NADPH and ATP produced are subsequently used to power the sugar-producing Calvin cycle.)

What are the roles of ATP and NADPH in the Calvin cycle quizlet?

What are the roles of ATP and NADPH in photosynthesis? Both of these molecules carry energy; in the case of NADPH, it has reducing power that is used to fuel the process of making carbohydrate molecules in light-independent reactions.

What do ATP and NADPH do in photosynthesis?

What is the difference between ATP and NADPH in Calvin cycle?

ATP is the energy source, while NADPH is the reducing agent that addshigh-energy electrons to form sugar. The Calvin cycle actually produces a three-carbon sugar glyceraldehyde 3-phosphate (G3P). For the Calvin cycle to synthesize one molecule of sugar (G3P), threemolecules of CO2 Must enter the cycle. The cycle may be divided into threephases:

What is the reducing agent in the Calvin cycle?

ATP is the energy source, while NADPH is the reducing agent that adds high-energy electrons to form sugar. • The Calvin cycle actually produces a three-carbon sugar glyceraldehyde 3-phosphate (G3P). Secondly, what is used in the Calvin cycle?

Where is RuBP used in the Calvin cycle?

In the animation of the Calvin cycle, three molecules of CO2 are added to three molecules of ribulose bisphosphate (RuBP), a 5-carbon sugar already present in the stroma. Click to see full answer. People also ask, where is ATP and Nadph used in the Calvin cycle?

Where do the reactions of the Calvin cycle take place?

Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts). This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.
