A statistical model of active ion transport in biomembranes was developed. The model makes it possible to calculate both the value of membrane potential phi zero and the rate of ion concentrations inside and outside the cell. These values depend on the difference of chemical potentials of the ATP-ADP system and the permeability of the biomembrane for ions being transported. The calculated phi zero value approximately 200-250 mV is consistent with the data on proton pumps.
建立了生物膜中活性离子转运的统计模型。该模型能够计算膜电位φ零的值以及细胞内外离子浓度的变化率。这些值取决于ATP - ADP系统化学势的差异以及生物膜对被转运离子的通透性。计算得到的φ零值约为200 - 250 mV，与质子泵的数据一致。
