Manganese is required for the photosynthetic oxygen evolution, where it has a central role in the charge accumulation process. Important information about the stability of accumulated charges and kinetics of induvidual steps can be obtained from the oxygen yield pattern after flash illuminating the material on an oxygen electrode. Velthuys and Kok (1) found that the oxygen yield pattern changed upon H2O2 tretment, and that this was due to a two electron donation from H2O2 to the oxygen evolving complex. Photooxidation of H2O2 has been shown to occur in photosystem II particles both in the dark (2,3) and in the light (1,4,5).
