Mathematical Models of Membrane Transport Processest of the important membrane transport problems remain unsolved. These unsolved problems are frequently based on complex molecular interactions which are poorly understood. One of the first tasks confronting an investigator is to separate out those portions of transport processes that can be adequate

Tracers in the Study of Membrane Processesntervals of the assumptions made in their daily use; that is, we usually act as though isotopes were simply labeled atoms, i.e., ideal tracers. An ideal tracer is an atom which differs in some measurable way from the normal atom but has properties identical with those of the normal atom. There are,

Principles of Water and Nonelectrolyte Transport across Membranesverton. and Collander and Bärlund.. Overton formulated the generalization that the rate of penetration of nonelectrolytes into plant cells was proportional to their oil-water partition coefficient. Collander and Bärlund. confirmed these observations but noted that, in certain instances, the cellular

Lipid Bilayer Membranes: Their Permeability Properties as Related to Those of Cell Membranesrt characteristics is perhaps the most essential, and certainly the most studied. One approach, with a long and distinguished tradition, for investigating this aspect of cell membranes is the building and analysis of model systems that emulate some of the properties of natural membranes. Of the mode

Electrically Neutral Ion Transport in Biomembranesl charges. To begin with, we consider the measurement of current flow across membranes, in order to show that some ion flows are not detected by this measurement technique. Then, we develop the physical—chemical ideas behind the formation of ion pairs, and discuss several examples relevant to ion fl

The Provision of Cellular Metabolic Energy for Active Ion Transport, directly or indirectly, by active transport, which is in turn sustained by energy derived from cellular metabolism. This chapter will address the nature of the process by which the metabolic energy of cellular metabolism is converted into the electrochemical energy of active ion transport, and it
