PSII also involve in
oxidation of water molecules, water is a very stable molecule that’s why Oxidation of water to form molecular oxygen
is very difficult, Many studies have provided a substantial amount of
information about the process known;

manganese (Mn) is an essential cofactor in the water-oxidizing process, and a classic hypothesis in photosynthesis research postulates that Mn ions undergo a series of oxidations—known as S states, This hypothesis has received strong support from a variety of experiments, which of the following techniques detect the manganese ions directly and Analytical experiments indicate that how much Mn ions are associated with each oxygen-evolving complex?

The detailed chemical mechanism of the oxidation of water to O2 is not yet well understood, but with structural information shows_one electron carrier, generally identified as Yz, functions between the oxygen-evolving complex and P680 to function in this region, Yz needs to have a very strong tendency to retain its electrons, this species has been identified as;
