In noncyclic photophosphorylation, electrons flow in a one-way path from water to A) ATP. B) O₂. C) NADP⁺. D) CO₂. E) sugar.

Question

Quizplus · Accepted Answer

In noncyclic photophosphorylation, electrons flow from water to NADP+ to form NADPH. ATP is also produced in this process through the generation of a proton gradient across the thylakoid membrane, but it is not the final electron acceptor. CHOICE A (ATP) and D (CO₂) are incorrect because they are not electron acceptors. CHOICE B (O₂) is a non-existent molecule. E (sugar) is incorrect because it is not involved in this process.
