During the Light-Dependent Reactions,NADPH ____

Question

During the light-dependent reactions,NADPH ____. A) is an enzyme B) is the oxidized form of NADP⁺ C) accepts hydrogen and electrons from water D) accepts hydrogen and electrons from carbohydrates E) obtains energy from ATP

Accepted Answer

During the light-dependent reactions, NADPH is produced by accepting hydrogen and electrons from water, which is split by the energy from light. NADPH is a reduced form of NADP+ and serves as an electron carrier for the light-independent reactions (Calvin cycle) where it donates its electrons to reduce CO2 to sugars. NADPH is not an enzyme and does not obtain energy from ATP or carbohydrates.
