The kinetics of changes in the membrane potential (φ), resistance (Rm) and membrane capacity (Cm) were compared with the modification of the structural and functional components of the plasmalemma of Nitellopsis obtusa cells. For the plasmalemma electrogenic pump, the following are established: short-circuit current 0.09 A/m2, internal resistance 4 Ohm×m2, electromotive force — 360 mV. The analyses of the kinetics of measuring φ, Rm, Cm during the modification of the structural and functional components of the plasmalemma revealed that the electrical capacity is an indicator of its lipid phase. The totality of established facts about the effect of standard modifiers on the main electrophysiological parameters of the plasmalemma indicates the presence of an organic relationship between the functional activity and the phase state of the lipid environment of the functional groups of the plasmalemma.
