Energetic parameters of the membrane of marine alga Acetabularia were compared at light and dark during the action potential (AP). Direct current resistance of the resting membrane at dark as well as at light is of the order 1000-5000 omega-cm2 without considerable difference. The maximum resistance of the excited Acetabularia membrane is somewhat increased(More)
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(More)
Concentration of K+-, Na+-, Mg++-, Ca++-, Cl-ions defined in Acetabularia crenulata cell was the same as that of Acetabularia mediterranea, both were cultivated under the same conditions. At the variations of the ionic composition of the external medium it has been shown that the potential of Acetabularia (A.) cell depends on K+-, Cl-ions and alga A. can(More)
