obsolete photosynthetic water oxidation (obsolete GO:0009781)
OBSOLETE. Processes by which a molecule of water is oxidized during photosynthesis. P680+, the photochemically oxidized reaction-center chlorophyll of PSII, is a strong biological oxidant. The reduction potential of P680+ is more positive than that of water, and thus it can oxidize water to give O2 and H+ ions. The oxygen escapes as a gas while the H+ ions remain in solution inside the thylakoid vesicle.
