Question

Electrons from excited chlorophyll of PS II are accepted first by

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

Answer 1

The correct option is A Quinone

Light reaction

Upon receiving light energy from the sun, the electrons of Photosystem II get excited and are accepted by pheophytin. Pheophytin then transfers the electron to quinone. Hence, among the given options, quinone is the first acceptor of electrons.

Hence, among the given options, quinone is the first to accept the electrons from photosystem II.

Final answer
(A) Quinone
