Coupling between simultaneous movements of carrier substrates

Summary

Countertransport and competitive acceleration were studied experimentally in the glucose system of the red cell membrane and theoretically by analysis of kinetics. It is shown that, although the conditions for demonstration of the two phenomena differ, they are related by a symmetric interdependence of the simultaneous movements of two substrates. The symmetry can be shown by different types of kinetic treatment. Using the phenomenological equations of nonequilibrium thermodynamics for the description, the cross-coefficients are found to be equal in accordance with Onsager's law.
