Electrons from an excited chlorophyll molecule of photosystem II are accepted first by
Ferredoxin
Cytochrome b
Cytochrome 7
Pheophytin
Pheophytin is the primary electron acceptor of non-cyclic photophosphorylation which accepts an electron from PS II and passes it to plastoquinone.
The first acceptor of electrons from an excited chlorophyll molecule of photosystem II is:
