Photolysis of water

Vedclass · Answer

(A) In the light-dependent reactions of photosynthesis,$PS-II$ (Photosystem $II$) plays a crucial role in the photolysis of water. When $PS-II$ absorbs light,it becomes excited and loses electrons. To replace these lost electrons,the oxygen-evolving complex associated with $PS-II$ splits water molecules $(H_2O)$ into protons $(H^+)$,electrons $(e^-)$,and oxygen $(O_2)$. This process is known as the photolysis of water,which provides the necessary electrons to maintain the electron transport chain.

The important function of $PS-II$ in photosynthesis is .........
