Chromatophore vesicles isolated from the photosynthetic bacterium Rhodospeudomonas sphaeroides R-26 were adsorbed as a film on SnO/sub 2/ electrodes and examined in a photoelectrochemical cell. The photovoltages and photocurrents generated by the cell under steady-state red light irradiation were dependent on the state of the chromatophores as modified by the chemical properties of the cell electrolyte including pH, salt concentration, redox couple, and redox potential. The cell was operable in the redox range where the c/sub 2/ cytochrome was reduced and the quinone pool was oxidized. Both these components are carriers in the cyclic electron transport system of bacterial photosynthesis and must control electron transport between the chromatophore membrane and the electrodes.
