True [87]

Answer:

ATP and NADPH

Explanation:

The second stage of the Calvin cycle is the reduction in which 3-Phosphoglycerate is reduced into Glyceraldehyde 3-phosphate by a series of reactions. These reactions consume ATP as an energy source and NADPH as an electron donor. ATP and NADPH for produced during the light-dependent phase of photosynthesis. Transfer of electron through ETC generates proton concentration gradient across the thylakoid membrane which in turn drives ATP synthesis. Electrons released from water splitting finally reach NADP reductase enzyme that reduces NADH into NADPH.
