Question

Which one in this figure will have highest redox potential?

• A. A
• B. B
• C. C
• D. D

Answer 1

The correct option is A A

Photosystem II has the highest redox potential and helps in oxidizing water molecules to gain electrons which were lost due to the action of photons on the PS II. These electrons lost from PS II are sequentially carried over across a chain of electron carriers down their reduction potentials.

So, the correct answer is, 'A'.
