Quizplus · Accepted Answer

NADP+ is a key electron acceptor in the production of NADPH during linear electron flow in the light reactions of photosynthesis. A reduction in the amount of NADP+ available would lead to a decrease in the rate of linear electron flow, as fewer electrons would be able to be passed along the electron transport chain. This would ultimately lead to a decrease in the production of ATP and NADPH, which would in turn impact the rate of the Calvin cycle, which depends on these energy-rich molecules for its function. Cyclic electron flow is not directly influenced by the availability of NADP+. Oxygen production is a result of the splitting of water molecules during photosynthesis and is not directly influenced by the availability of NADP+.
