  • Title: [Comparison of the energy characteristics of Acetabularia membranes in light and darkness].
    Author: Ksenzhek OS, Apostolova RD.
    Journal: Biofizika; 1975; 20(4):656-60. PubMed ID: 1201300.
    Abstract:
    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 at dark as compared to its value at light. The maximum power of the membrane system and that of its regulating mechanism along with the energy dissipating AP at light exceed the same values at dark. The dissipating energy and the work Acetabularia cell performs during the AP are also compared for light and dark conditions.
