[Kinetics of triphosphoglyceric acid formation in Chlorella pyrenoidosa (in vivo) during alternation of light and darkness]

Abstract

On the basis of specific features of carbon reduction cycle in photosynthesis (Kalvin cycle or reduction pentosophosphate cycle) and other processes, in which triphosphoryglyceric acid (3PGA) is an intermediate product, and taking into account the available data concerning the reaction of 3PGA pool of Ch. pyrenoidosa (in vivo) to light-dark disturbances approximate kinetic curves of the value of ribulosodiphosphate (RuDP)--carboxylating reaction product and of other 3PGA accumulations in the chloroplast strom aunder light-dark disturbances. Proceeding from the pecularities of these curves a hypothesis is advanced to the effect of some connection mechanisms of photosynthetic and glycolytic processes of 3PGA production.
