Which of the following sequences correctly represents the flow of electrons during photosynthesis? A) H₂O -NADPH - Calvin cycle B) NADPH - O₂-CO₂ C) NADPH -chlorophyll -Calvin cycle D) NADPH -electron transport chain - O₂ E) H₂O -photosystem I -photosystem II

Question

Quizplus · Accepted Answer

During photosynthesis, electrons flow from water (H2O) to NADPH and then to the Calvin cycle. Water is split to release electrons, which are transferred through photosystems and the electron transport chain, ultimately reducing NADP+ to NADPH. This NADPH is then used in the Calvin cycle to fix carbon dioxide into sugars.
