Splitting of water is associated with

Options

A. photosystem I
B. lumen of thylakoid
C. both photosystem I and II
D. inner surface of thylakoid membrane

Answer

D

Explanation

Light reactions occur inside the thylakoids, especially those of grana region. It involves two types of reactions photolysis of water and production of assimilatory power. Oxygen in the illuminated chloroplasts is called photolysis or photocatalytic splitting of water. Water spilitting complex is associated with the PSII, which iteself is physically located on the inner surface of thylakoid membrane.
