An outer membrane surface is assumed to take up potassium ions in a manner analogous to adsorption. This model, already successful in predicting transmembrane flux, is shown to predict also an asymmetrical potential-time relation depending on the direction of the concentration changes. The results may have some value in explaining recent observations of similar effects in muscle.
