[Kinetic model of primary processes of photosynthesis in chloroplasts. Fast phase of chlorophyll fluorescence induction under light of various intensity].
A kinetic model was developed, which describing the system of generation and consumption of the transmembrane electrochemical proton potential delta mu H+ in primary photosynthetic processes. The model describes the catalytic cycles of photosystems I and II and the cytochrome b/f complex, as well as the ATP synthesis and passive leakage of H+, K+ [symbol: see text] Cl- ions through the thylakoid membrane. The dependence of the electron transfer rates on the value of transmembrane electric potential was taken into account. The model was applied to describe the experimental data on the registration of the fast phase of fluorescence induction. The model gives a realistic description of the fast phase of induction curves at different light intensities (from high to low).
