[Biophysical primary processes in photosynthetic membranes. Data with pulse-spectroscopical methods].
The electron transfer in the photosynthetic membrane of green plants from H2O to NADP+ is driven by two chlorophyll reaction centers in series. The electron transfer converts one part of the light energy into the form of the reducing power of NADPH. The transfer initiates an electrical field across the membrane. The electrical energy of the charged membrane is an additional state into which light energy is converted. Protolytic reactions coupled with the electron transfer lead to a proton translocation into the inner space of the thylakoid. The discharging of the ectrically energized membrane by H+ efflux is coupled with the formation of ATP.
