Abstract

The presence of an electric field in a membrane creates stresses which lead to a mechanical compression of the membrane material. It is shown that considerations of this effect yield results consistent with the observed differential effect of pH on the plasma membrane substructure if the central electron-lucent layer in OsO4-fixed membranes is identified with the ionic depletion in the double-fixed charge model of cell membranes.
