Thermodynamic treatment of radio-tracer movements across biological membranes.
The movements of radioactive tracers across living cell membranesare discussed on the basis of thermodynamics of irreversible processes. Krogh's equation describing the flux of a tracer as a function oftime is derived, and the significance of the "permeability" constant is clarified.
