Proton-motive force maximal value

The maximal value that the proton-motive force can reach is limited by the redox potential difference ( A q) between the electron donor and acceptor and by the total number of protons (n) translocated per two electrons transferred ... [Pg.262]

Upon illumination a proton motive force is generated in whole cells, chromatophores and membrane vesicles. In membrane vesicles a proton motive force is generated which is inside alkaline and negative. The ApH, determined from the distribution of acetate, depends on the composition of the medium and is maximally 0.6 at an external pH of 7 the Aijj, measured from the distribution of triphenylmethyl phosphonium is about -70 mV. The proton motive force in membrane vesicles can thus reach values of around -110 mV (Michels, Konings, 1978). [Pg.349]
