The final acceptor of electrons during the non-cyclic electron pathway is:
Correct answer: D. NADP+
- A. Photosystem I
- B. Photosystem II
- C. ATP
- D. NADP+
Explanation
NADP+ acts as the final electron acceptor during non-cyclic electron flow, while electrons are moved back from ferredoxin to the cytochrome complex to generate assimilating power via cyclic electron flow.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
