Answer :
The light reactions require the cooperation of two photosystems to power linear electron flow from water to NADP. The statement is True.
ONLY PHOTOSYSTEM 2:
-water oxidation
-shortening of the electron transport chain between the two photosystems
ONLY PHOTOSYSTEM 1:
-NADP+ decrease
-oxidation of the electron transport chain connecting the two photosystems
BOTH THE PS2 AND THE PS1:
-absorption of light
-decrease in primary electron acceptor
[The primary job of each photosystem is to absorb light and convert the absorbed light's energy into redox energy, which drives electron transport.
- P680 is oxidized (which oxidizes water) in PS II (the first photosystem in the sequence), and the PS II primary electron acceptor is reduced (which in turn reduces the electron transport chain between the photosystems).
-The PS I primary electron acceptor is reduced (which in turn reduces other molecules, finally reducing NADP+ to NADPH), while P700 is oxidized (which oxidizes the electron transport chain between the photosystems)].
