Question

Electrons from excited chlorophyll molecule of photosystem- II are accepted first by

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

Answer 1

The correct option is A Quinone.

Photosystem- II is involved in non-cyclic photophosphorylation with a reaction center P${}_6$${}_8$${}_0$. The electrons excited from P${}_6$${}_8$${}_0$ are accepted by plastoquinoine.
