[Mechanical oscillations and dynamic organization of biomembranes].

Biological membranes are considered as mechanochemical active media. A hypothesis is advanced according to which the biomembranes are dimeric distributed non-equilibrium systems. They provide conjugated functioning of energy transducers by means of mechanical oscillations. Transmembrane currents of substance and energy stimulate in the membranes modes determining space and time organization of the membranes characteristic of dissipative structures. The mechano-chemical conjugation of all the processes is suggested to be the physical basis of their cooperativity. Critical wavelengths for basic modes and their energetic parameters are evaluated.
