We need to determine the correct order of electron flow in the light-dependent reactions of photosynthesis and then evaluate how well each provided option aligns with that order.
First, recall the commonly accepted sequence of events in the light-dependent reactions: photons activate PSII (step 2), which drives water splitting to replace electrons (step 1). The electrons then pass through the cytochrome b6-f complex (step 4), after which they reach PSI where photons excite PSI again (step 3). Finally, electrons are transferred to NADP+ via NADP+ reductase (step 5). Therefore, the canonica......Login to view full explanation登录即可查看完整答案
