Abstract
Tracer efflux measurements (86Rb+ and2NaNa+) were performed on resealed human erythrocyte ghosts at different intra- and extracellular NaCI concentrations. Using a modified Goldman equation the observed alterations of the rate constants could be explained by taking into account the transmembrane and surface potentials, at constant permeability coefficient . These results emphasize the importance of membrane surface potentials in triggering ion transport across biological membranes.
