Photosystem I (PSI) and photosystem II (PSII) have similarities and differences.Which statement comparing these two systems is false? A) PSI and PSII have reaction center chlorophylls that absorb light at different wavelengths. B) Both PSI and PSII reaction centers draw electrons from electron donors after they are excited by photons and oxidized. C) The excited chlorophyll (Chl*) of a PSII reaction center loses an electron and is re-reduced by water, while the Chl* of a PSI reaction center passes its electrons via intermediates to NADP⁺. D) The energy trapped in the excited states of both PSI and PSII is used to reduce NADP⁺. E) PSII and PSI are both located in the thylakoid membrane along with the electron transport chain.

The energy trapped in the excited states of PSI is used to reduce NADP+ to NADPH, while PSII's primary role involves splitting water and generating a proton gradient for ATP synthesis, not directly reducing NADP+.
