The process of the ions transport through the biological membrane is considered. A role of air microbubbles efficiently mixing a near-membrane liquid layer in the presence of a temperature gradient is pointed out. These circumstances result in lowering an energy barrier height of the transmembrane ion-transport. It is shown that even low-level irradiation by the millimeter waves creates the temperature gradient, which is enough for effective mixing of near-membrane liquid's layer. It is demonstrated that a process of restoration an equilibrium air-distribution in the intercellar medium after ceasing the microwave irradiation proceeds according to the diffusion mechanism, i.e. rather slow.
