[Energy parameters of Acetabularia cell membrane].
The energy parameters of the mechanism involved in the action of Acetabularia cell membrane were studied. The resistance of the membrane is found to be near 3 kohm per sq. cm when resting and at the peak of excitation it is much lower (100 ohm/cm(2). The power of the mechanism regulating the action of the membrane during the peak. The total power of the membrane system of Acetabularia is 8 microwatt per sp. cm. reaches 6.5 microwatt/cm(2). The energy consumed by the regulatory mechanism during the action potential is minus 290 plus or minus 20 erg/cm(2) and the total energy dissipation is 20 erg/cm(2). The values of the energy consumed by the cell during the action potential are compared with its energy resource.
