[Photophosphorylation sensitized by chlorophyll in the adsorbed state].

Products of phosphate oxidation in a weak alkaline medium in the electrolysis and in the reaction, photosensitized by chlorophyll, are studied. It is shown that besides perphosphates, pyrophosphate can be formed under electrochemical phosphate oxidation. Phosphate was used as an electron donor and the air oxygen was an electron acceptor in the red-ox reaction, photosensitized by chlorophyll. The reaction was accompanied by the decrease of inorganic phosphate content in the reaction medium and by the phosphorylation of ADP to ATP. The mechanism of photophosphorylation is discussed on the basis of the data obtained.
