The kinetic parameters of photoexcitation and relaxation of reaction centres (RC) of photosynthetic membranes of the Rhodobacter sphaeroides cells are determined for different modes of photoexcitation. The model of a slow electron transport and conformational changes in RC is proposed as a system that can be described by four electron-conformational states with constant microrates. For the first time, the numerical values of microrates of the RC oxidation and reduction processes are obtained, and populations of the 2nd, 3rd, and 4th electron-conformational states are calculated, based on population of 1st state.

Key words: reaction centre, electron transport, conformational change.
