NADPH is generated in the light-dependent reactions as a powerful reducing agent. In the Calvin cycle, it is responsible for the reduction of 1,3-bisphosphoglycerate (1,3-BPG) into glyceraldehyde-3-phosphate. Reduction in this context can be defined as the addition of electrons. If you are familiar with organic chemistry, it is very hard to reduce a carboxylic acid (glycerate is a carboxylic acid) directly to an aldehyde (glyceraldehyde is an aldehyde) directly. Even if we go through the primary alcohol intermediate, it still involves very nasty reagents such as LiAlH4 (lithium aluminum hydride) and Collins reagent (chromium (VI) oxide with pyridine) which are extremely damaging and toxic to living organisms. Plants, however, overcomes this difficulty with clever use of activation by phosphorylation (with ATP) and then an NADPH reduction catalyzed by G3P dehydrogenase.

What is a product of the light reactions of photosynthesis that are utilized in the Calvin cycle?
ATP and NADPH are the products utilized in the Calvin Cycle.
What goes into the Calvin cycle ( photosynthesis)?
There are two products. Those are NADPH and ATP.
Are nadph and ATP produced by the Calvin cycle?
Yes, they carry energy between the light reactions and the Calvin cycle. ADP is phosphorylated into ATP at the ATP synthase while NADP is reduced by the electrons in the transport chain (it then becomes NADPH).
What is the name of the molecule that carries electrons from the light dependent reactions to the Calvin cycle?
ATP (adenine tri-phosphate)
What products of the light reactions are used up in the Calvin cycle?
NADPH and ATP
What is a product of the light reactions of photosynthesis that are utilized in the Calvin cycle?
ATP and NADPH are the products utilized in the Calvin Cycle.
What does NADPH add to the Calvin-Benson cycle?
NADPH adds electrons to the Calvin-Benson cycle.
The Calvin cycle is dependent upon a supply of?
The Calvin cycle is fueled by ATP and NADPH produced in the light reactions.
What goes into the Calvin cycle ( photosynthesis)?
There are two products. Those are NADPH and ATP.
What are the reactant of the Calvin cycle?
ATP, NADPH, and CO2
Are nadph and ATP produced by the Calvin cycle?
Yes, they carry energy between the light reactions and the Calvin cycle. ADP is phosphorylated into ATP at the ATP synthase while NADP is reduced by the electrons in the transport chain (it then becomes NADPH).
What are the substances used Calvin cycle?
The Reactants for the Light-Independent Cycle(Calvin Cycle) are ATP, CO2, and NADPH
What does the Calvin cycle do?
The Calvin cycle uses carbon from carbon dioxide (CO2) to form carbohydrates.
What does light dependent reactions supply the Calvin cycle with?
Light reactions provide ATP and NADPH to the Calvin Cycle, and the cycle returns ADP, Pi, and NADP+ to the light reactions.ATP and NADPH are produced by the light reactions of photosynthesis and consumed by the Calvin cycle.
What is produced by noncyclic photophosphorylation and used by the Calvin cycle?
ATP and NADPH
Which energy carrier directly supplies to Calvin cycle?
atp and nadph
How do the reaction help the Calvin cycle?
Light reactions produce NADPH and ATP, which are used during the Calvin cycle.
