    Abstract:
    A method for multiparticle computer simulation of photosynthetic electron transport in a thylakoid membrane has been developed. The basic principles of this method were described previously. The method is used to describe the cyclic electron flow around photosystem I. The effects of size and shape of the reaction volume on the kinetics of interaction of a mobile carrier with a protein complex and the limited diffusion of reactants were studied. It was shown that the kinetic parameters of photosynthetic electron transport processes depend on the distribution of protein complexes in the membrane. It was shown that the limited nature of diffusion of plastoquinone molecules in the membrane leads to a tenfold decrease in the efficient diffusion coefficient. It was shown that the occurrence of two phases of dark reduction of photooxidized P700+ is due to a heterogeneous spatial organization of the thylakoid membrane of a chloroplast.
