Summary:An experimentally discovered relationship between transmembrane and electrokinetic potentials has been examined. The redistribution of transmembrane potential between the capacitances of the membrane and of the electric double layer as well as the change of cell surface charge under membrane energization were interpreted as the reasons for this relationship. The surface charge change may stabilize the intramembrane field to make it optimal for the functioning of membrane bioenergetic systems, as well as to prevent the membrane electrical breakdown under fluctuations in the transmembrane potential.
