title: [Mathematical and computer modeling of primary processes of photosynthesis].
abstract: The results of recent works on kinetic and direct multipartial computer modeling of processes in the photosynthetic membrane, performed at the chair of biophysics of the Biological faculty of the Moscow State University are reviewed. The models take the current experimental data on the heterogeneous structure and kinetic characteristics of the system into account. The generalized kinetic model describes the processes in multienzyme complexes of Photosystems 1 and 2 and the cytochrome complex, coupled transmembrane ionic currents, and the generation of electric and electrochemical potential. The identification of the parameters of the models allows one to estimate the rate constants for reactions that cannot be measured experimentally. The multicomponent models give a clear picture of the interaction of components of the electron transport chain in the lumen and the tylakoid stroma and simulate in an explicit form the Brown diffusion and electrostatic interactions of protein carriers. The combination of different methods of description (differential equations and formalism of Brown dynamics) allows one to model the processes in a complex three-dimensional interior of a vegetative cell that collectively provide a high efficiency of energy transformation in photosynthesis.
