Which of the following describes the correct sequence of electron flow in non-cyclic photophosphorylation?
Show answer and explanation
Correct answer: P680 → Electron Transport Chain → P700 → NADP+
Electrons are first excited in PS II (P680), pass through a series of electron carriers (ETS), reach PS I (P700), are excited again, and finally reduce NADP+ to NADPH.
