[Kinetic pattern of a model of a calcium channel with 2 conformational states]

A kinetic scheme of the organization of ion-transport processes in the calcium channel is suggested and analytical expressions for mixed current of monovalent and divalent cations are obtained on its basis. This model predicts the reversal potential for the calcium current when intracellular solution contains monovalent cations and the anomalous behaviour of the mixed current of divalent cations depending on the mole fraction.
