Coupling between chemical reactions and transport phenomena can cause the substrate concentration at the surface of a membrane to be lower on the substrate-rich side than the substrate-lean side. Thus, the diffusing flux inside the membrane may be counter to the overall external concentration driving force. Graphical solutions of various steady states of such membranes are presented.
