Q. The first acceptor of electrons from an excited chlorophyll molecule of photosystem II is
A) iron-sulphur protein
B) ferredoxin
C) quinone
D) cytochrome
Explanation
[Solution from source] Electrons from P680 pass to the primary acceptor of PSII and then to plastoquinone, so among the options a quinone is the first acceptor. Ferredoxin and iron-sulphur proteins accept electrons on the PSI side, and cytochromes come later in the chain. Answer (3).
