Question : Describe photolysis of water.

1.	Question : Describe photolysis of water.
Answer» Solution :The electrons that were moved from photosystem - II have to be replaced. This is achieved by electrons available due to spliting of water Explanation of the process : The splitting of water is associated with the PS-II, water is split into `H^(+)`, [O] and electrons. `2H_(2)O rarr 4H^(+) + O_(2) 4e^(-)` This creates oxygen, one of the net products of photosynthesis. The electons NEEDED to replaced those REMOVED from photosytem - I are provided by photosystem - II. Water splitting complex is associated with th PS II, which itself is physically located on the inner side of the MEMBRANE of the thylakoid.
