Question

Electrons from excited chlorophyll of PS II are accepted first by

• A. Quinone
• B. Ferredoxin
• C. Cytochrome b
• D. Cytochrome f

Answer 1

The correct option is A Quinone

A) Electrons from excited chlorphyll molecule of photosystem II are accepted first by Quinone.

B) Ferredoxin is an electron carrier. During photosynthesis, electrons are removed from water and transferred to ferredoxin.

C) Cytochrome b is a protein found in the mitochondria of eukaryotic cells. It functions as part of the electron transport chain.
D) Cytochrome f is the largest subunit of the cytochrome complex. It functions as part of the electron transport chain.
So the correct answer is 'Quinone'.
