PHOTOSYNTHETIC OXYGEN - THE ROLE OF H2O2 - A REVIEW

Photosynthetic oxygen is currently believed to be derived from water. A number of H2O analogs interact with the water-oxidizing complex. Of special interest among them is hydrogen peroxide in view of its possib le involvement in photosynthetic O-2 production. Presumably, H2O2 repr esents an intermediate product of H2O oxidation and plausibly even the primary electron donor. In some cyanobacteria and algae, O-2 evolutio n is abolished under anaerobic conditions. Investigation of the role o f H2O2 in photosynthetic O-2 evolution is a promising field of researc h.
