Effects of Triphosphopyridine Nucleotide upon Oxygen Evolution and Carbon Dioxide Fixation by Illuminated Chloroplasts

Abstract

THE illumination of suspensions of chloroplasts always causes a very small and transient evolution of oxygen. The rate curve for this process has previously been measured1 under anaerobic conditions by means of the phosphorescence quenching method of Franck and Pringsheim2. In continuation of this work, the influence on oxygen production of certain biologically important substances added to the chloroplast suspensions has been studied.
