Computation of variation of general and partial free energy, exemplified by intracellular transport of calcium ions performed by sarcoplasmic reticulum Ca(2+)-ATPase, is used to demonstrate that the system of active transport of calcium ions works effectively even if transmembrane difference of electric potentials is absent. The possibility that local redistribution of charges on molecules complexes influences the Ca2+ transfer, is discussed.
