The energy carriers NADPH and NADH differ structurally. Functionally they
A)are quite similar; each transports electrons and hydrogen ions released in catabolic pathways.
B)are quite similar; each transports electrons and hydrogen ions to anabolic pathways.
C)are somewhat different; NADPH receives electrons and hydrogen from catabolic processes, whereas NADH delivers those items to anabolic processes.
D)are somewhat different; NADH receives electrons and hydrogen from catabolic processes, whereas NADPH delivers those items to anabolic processes.

Question

Quizplus · Accepted Answer

NADH is primarily involved in catabolic reactions, such as cellular respiration, where it carries electrons to the electron transport chain. NADPH, on the other hand, is used in anabolic reactions, such as photosynthesis and biosynthetic pathways, where it provides the reducing power needed for the synthesis of biomolecules.
