The exchange of oxygen during NADP+ photoreduction by isolated pea chloroplasts was studied. It was found that NADP+ oxidation is accompanied by oxygen photoreduction preceeding at a high rate. A possibility for calculation of the ration between the pseudocyclic electron transport and the total electron transport based on oxygen exchange in the presence of NaN3 and catalase, was established. It was found that the pseudocyclic transport can make up to 30% or more of total electron transport.
