Q. Photolysis of each water molecule in light reaction will yield :

Q. Photolysis of each water molecule in light reaction will yield :

(a) 2 electrons and 4 protons

(b) 4 electrons and 4 protons

(c) 4 electrons and 3 protons

(d) 2 electrons and 2 protons

Solution:

Correct option : D 
Photolysis is part of the light-dependent reactions of photosynthesis. The general reaction of photosynthetic photolysis can be given asH2AH2A + 2 photons (light) → 2 e−e− + 2 H+H+ + A So, the correct option is ‘Option D’.
