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

Question

Quizplus · Accepted Answer

In photosynthesis, water (H2O) is split in the light-dependent reactions to provide electrons, which are then used to reduce NADP+ to NADPH. NADPH is subsequently utilized in the Calvin cycle to help convert CO2 into glucose.
