Quantitatively, ions and water dominate the transport activity of most epithelia. Although the species of ions transported and the direction of transport may differ, this diversity of function seems to be achieved through the co-ordinated activity of a relatively small number of transport proteins (pumps, carriers and channels), which are combined in different proportions and at different cellular locations (i.e. apical or basolateral membranes) in different epithelia. Those commonly involved are listed in Table 1 . A general description of the function and regulation of these transport proteins has been published elsewhere [ 11, while a detailed description of some of them follows in this

Study the Transport Properties of Anion and Cation Exchange Membranes toward Various Ions Using Chronopotentiometry

The transport properties of various anion and cation exchange membranes were studied in different electrolyte solutions using chronopotentiometry technique to get insight about the influence of the counter ion on the transport properties of the membranes. The investigated samples include heterogeneous ion exchange membranes varying in the functionality of fixed charged gro...
