In which of the following ways is photosystem I different than photosystem II?
A. Photosystem I uses the high-energy electrons to reduce NADP to NADPH, whereas photosystem II uses them to produce ADP into ATP.
B. Photosystem II contains a pigment complex to trap energy, whereas photosystem I does not.
C. Photosystem II captures solar energy, whereas photosystem I does not.
Answer (2)
Photosystem I differs from Photosystem II primarily in that it reduces NADP+ to NADPH using high-energy electrons, while Photosystem II converts ADP into ATP. Also, Photosystem II captures solar energy with a pigment complex, which Photosystem I does as well but with a different focus. Thus, both systems have distinct roles in the photosynthetic process. ;
Photosystem I reduces NADP+ to NADPH, while Photosystem II converts ADP into ATP, highlighting their different functions in photosynthesis. Photosystem II captures solar energy, which makes it distinct in the photosynthetic process. Therefore, the correct option is A.
