Question

2H2O 2H+ + O2 + 4e–

a) Where in plants does this reaction occur?

b) What is the importance of this reaction?

Answer 1

answer:

a) In the reaction centre, PS II, situated in the inner surface of the thylakoid membrane. Here electrons are extracted from water and are known as water splitting centre, and is catalyzed by the Mn+ and Cl– ions.

b) The process releases molecular oxygen as a by-product of photosynthesis and is an important source of oxygen in the air, for living entities on earth. The ions of hydrogen hence produced are used in reducing NADP to NADPH which is a strong reducing agent. It creates a gradient for the synthesis of ATR when electrons released are transferred from PS II to PS I through electron carriers.
