[Effectiveness of energy transformation during active transport of ions in a biomembrane].

A statistical model of active ion transport in biomembrane is presented. The coefficient of energy conversion for linear and nonlinear processes in this system is obtained. It is shown that in the linear case this coefficient equals to the one obtained in linear thermodynamics. Based on the maximum of this coefficient, the transport parameters for ions are found. The results of the statistical model are in good agreement with experiments on biological membranes.
