Abstract : The exchange between ADP and ATP found in chloroplasts was concluded to be unrelated to the process of photophosphorylation. Photophos phorylation coupled to the reduction of in dophenol dyes was demonstrated. The complex role of indophenol dyes in inhibiting, eliciting, or bring about lag periods in photophosphory lation reactions was clarified. Previous studies on the path of oxygen atoms in photophosphory lation were extended. The effect of irradiating chloroplasts with uv light on their photochemical activity was studied. A sensitive method for measuring the reduction of ferricyanide in photo chemical and other enzymatic reactions was de veloped. A factor which specifically restores the ability to phosphorylate, was isolated from chloroplasts. (Author)
