What is the most important function of PS II?

Explanation

The most important of PS II is splitting of water and evolution of molecular oxygen. First of all, the light falls on PS II and the reaction center of PS II (i.e., `P_(680)`) gets excited. The excited reaction center reduces quinone and gets oxidized. The oxidized `P_(680)` then gets electrons from water. The electrons from quinone move to electron transport chain.
