BotanyDuring non-cyclic electron transport of photosynthesis of higher plants, A is the ultimate electron donor and B is the ultimate electron acceptor. A and B are, respectively,

During non-cyclic electron transport of photosynthesis of higher plants, A is the ultimate electron donor and B is the ultimate electron acceptor. A and B are, respectively,

A
P680 and P700
B
$P 680 and {NADP}^{+}$
C
$H_{2} O and {NADP}^{+}$
D
$H_{2} o and ferridoxin$

Solution:

In non-cyclic electron transport of photosynthesis of higher plants, the electrons of water ultimately reach ${NADP}^{+}$ to form NADPH after passing through Mn, tyrosine or $Y_{z}$ , P 680, pheo, $Q_{A}, Q_{B}$ , PQ, Fe.S protein, cytochrome f, plastocyanin, P700, $A_{0}, A_{1}, F_{x}, F_{A / B}$ , ferredoxin, and FNR enzyme.
