Answer #1

The photolysis or oxidation of water occurs by a protein complex called as Oxygen evolving complex (OEC). This complex is located in photosystem II (PSII) in the thylakoid membrane. Splitting of two water molecules yields four electrons, four protons and molecular oxygen.

2H2O   4H+ + 4e- + O2

The electrons are then passed to PSII one by one through a series of oxidation states of the OEC. An electron carrier called Yz carrier functions between OEC and PSII.
