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;

which of the following are false ?

#Unit 6. System Physiology – Plant
  1. The photosynthetic oxygen-evolving complex is the only known biochemical system that carries out water oxidation process
  2. The protons produced by water oxidation are released into the lumen of the thylakoid, not directly into the stromal compartment because of the vectorial nature of the membrane
  3. The fact that the oxygen-evolving complex is localized near the exterior surface of the thylakoid membrane
  4. The protons produced by water oxidation are eventually transferred from the lumen to the stroma by translocation through the ATP synthase, In this way, the protons released during water oxidation contribute to the electrochemical potential driving ATP formation.
