Moreover, artificial membranes are now available to serve as suitable models to study special features of biological membranes. Still, the connections between morphological features and transport beh

Apparently such interaction involves a specific component of the membrane, which in essence functions as a “mediator” of the translocatio

Isotope Interaction — Tracer Couplingith fixed of mobile membrane constituents (solute-membrane interactions), have been disregarded. In biological membranes, however, a penetrating solute particle is likely to interact with other moving particles, either of the same, or of a different solute species. Such interactions may be direct, e

The flow of a single solute, in the absence of nonconjugate forces, should be proportional to the conjugate driving ., and inversely proportional to a resistance coefficient. The force is conventionally defined as the gradient of the electrochemical potential of
