As discussed in

Photolysis of water -

Occurs in the lumen of thylakoid. Requires Mn+, Cl-, Ca2+ and oxygen evolving complex 

- wherein

2H_{2}O\rightarrow 4H^{+}+4e^{-}+O_{2}

e- move towards P680 of PSII and H+ accumulate in lumen and finally reduced to NADP

 

 Mn^{2+} is required for photolysis of water
