Mathematical modeling is the basis for analyzing the regulation of photosynthetic electron transport in chloroplasts. This article provides a brief overview of our models of oxygenic photosynthesis in the context of the pH-dependent regulation of electron transport in chloroplasts. Alternative electron transport routes, transthylakoid proton transport, and ATP synthesis are analyzed. The models consider the mechanisms of pH-dependent control of electron transfer and activation of the Calvin – Benson cycle. Kinetic curves illustrating the processes of photosynthesis control in chloroplasts adapted to darkness (low initial Calvin – Benson cycle activity) have been obtained. The mathematical modeling of electron and proton transport processes in oxygenic photosynthetic systems performed in this work has made it possible to adequately describe the kinetics of redox transformations of P700, plastoquinone, plastocyanin, ferredoxin, and other electron carriers, as well as photoinduced pH changes in the lumen and stroma, and to analyze the contribution of alternative electron transport routes to electron and proton transport processes.
