KCl solutions separated by a membrane in The K+ and Cl– ions will permeate the membrane independently as they diffuse down their respective gradients of electrochemical potential, In biological systems, membranes are usually more permeable to K+ than to Cl–. Therefore, K+ will diffuse out of the cell  faster than Cl–, causing

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;
