1. Chlorella cells and spinach chloroplasts, whose catalase activity had been more than 90% inhibited by 10^<-5>M azide, were found to decompose H_2O_2 photochemically to liberate oxygen, indicating that H_2O_2 was used as an oxidant of the HILL reaction. 2. That, however, the observed phenomena cannot be fully accounted for in terms of the HILL reaction with H_2O_2, was revealed by the observation that an extract of Chlorella cells, which had been completely freed from chlorophyll, also showed a light-accelerated O_2-evolution from H_2O_2 in the presence of 10^<-5>M azide. This extract contained a large quantity of catalase, which seemed to have been, in some way, involved in the reaction in question. 3. The catalatic H_2O_2-decomposition caused by crystalline catalase of mammalian liver (in the presence of 10^<-5>M azide) was not accelerated by the effect of light.
