|
Electrons from the excited chlorophyll molecules of PS-II are first accepted by ____
|
|
Pheophytin
|
|
|
Ferredoxin
|
|
|
Cytochrome f
|
|
|
Cytochrome b
|
Explanation:
Detailed explanation-1: -So the correct answer is ‘Quinone’.
Detailed explanation-2: -Plastoquinone is the first acceptor of electrons from an excited chlorophyll molecule of photosystem II.
Detailed explanation-3: -Pheophytin is the primary electron acceptor of non-cyclic photophosphorylation which accepts an electron from PS II and passes it to plastoquinone.
Detailed explanation-4: -Pheophytin is the primary electron acceptor for PS II. It picks up the electron given out by P680 and passes it to the next electron acceptor plastoquinone, which further passes it to the cytochrome complex.
Detailed explanation-5: -Ferredoxin is the iron-containing sulphur protein, which is the first pigment that accepts electrons.
