Explain the splitting of water.

(N/A) - The electrons that are removed from photosystem-$II$ $(PS-II)$ must be replaced.
- This replacement is achieved by electrons made available through the splitting of water.
- The splitting of water is associated with $PS-II$; water is split into protons $(H^{+})$,nascent oxygen $([O])$,and electrons $(e^{-})$.
- The chemical equation for this process is: $2H_{2}O \longrightarrow 4H^{+} + O_{2} + 4e^{-}$.
- This process releases oxygen,which is one of the net products of photosynthesis.
- The water-splitting complex is physically located on the inner side of the thylakoid membrane,associated with $PS-II$.
