In linear (non-cyclic) electron flow, electrons go from
- Acheck_circle
PSII (P680) to electron transport chain to PSI (P700) to NADP⁺
- B
PSI (P700) to electron transport chain to PSII (P680) to NADP⁺
- C
ATP synthase through the electron transport chain to PSI
- D
NADPH back to PSII through the cytochrome complex to oxygen
Explanation
Electrons travel from H₂O → PSII → ETC (pumping H⁺) → PSI → ferredoxin → NADP⁺ to make NADPH.
