Which of the following statements concerning cyclic photophosphorylation is FALSE?
A)Only PSI is used.
B)Plastocyanin is oxidized by the photosystem.
C)NADPH donates electrons to the plastoquinone pool.
D)Ferredoxin accepts electrons from the photosystem and reduces the cytochrome bf complex.
E)This system is used to pump protons and form an electrochemical gradient to drive the formation of ATP.
