Adenine nucleotide status, phosphoglycerate reduction and photosynthetic phosphorylation in a reconstituted chloroplast system

Abstract
The concentrations of ADP and ATP were measured during illumination of a reconstituted chloroplast system to which NADP+, 3-phosphoglycerate and ribose 5-phosphate were successively added. Their effects on photosynthetic oxygen evolution and on the concentrations of ATP and ADP are discussed in terms of the regulation of photosynthetic carbon assimilation.
