As an energy carrier, ATP differs from NADPH in that
A) ATP carries less energy than NADPH.
B) ATP transfers energy through redox reactions whereas NADPH uses phosphorylation.
C) NADPH is involved in a larger variety of chemical reaction than ATP.
D) NADPH is made by Photosystem I whereas ATP is made by Photosystem II.

Question

Quizplus · Accepted Answer

ATP carries less energy than NADPH. Despite both being energy carriers, they differ in the type of energy they carry and transfer. ATP transfers energy through the transfer of phosphate groups, whereas NADPH transfers energy through the transferring of electrons. NADPH carries more energy than ATP, making it a more potent reducing agent.
