Quizplus · Accepted Answer

Both NAD+ and NADP function as electron carriers in cells, but the difference between them is that NADP has a phosphate group attached to its ribose ring, whereas NAD+ does not. This phosphate group allows NADP to participate in different metabolic reactions that require the transfer of high-energy electrons, such as photosynthesis. NAD+ is primarily involved in catabolic reactions, where it accepts electrons and becomes reduced to NADH, which is then used to produce ATP through the electron transport chain.
