Membrane potential and Donnan potential

Biophysical Chemistry, 1988
The Nernst-Planck-Poisson equations for the potential profile across a membrane are exactly solved without recourse to the assumption of constant field within the membrane. It is assumed that the membrane core of thickness dc is covered by a surface layer of thickness ds in which the membrane-fixed charges are distributed at a uniform density N.

Membrane potentials for keratin

Journal of Colloid Science, 1947
Abstract Measurements of the membrane potentials of keratin membranes have been made using KCl and NaCl and the results show how the selectivity of the membranes can be altered by soaking in suitable buffer solutions. The results support Toerell's theory of membrane behavior in neutral salts, and some membrane potential measurements using HCl ...

Membrane potential of bipolar membranes

Journal of Electroanalytical Chemistry, 1996
Abstract The membrane potential of a bipolar membrane composed of a cation-exchange layer in series with an anion-exchange layer is analyzed theoretically and experimentally. The theoretical approach is based on an extension of the Nernst-Planck equations of monopolar charged membranes to the case of the two ion-exchange layers in series and the ...

Negative membrane potentials potentiate multicellularity

BioSystems
Why did evolution almost exclusively select negative membrane potentials? Why did natural selection not favour positive membrane potentials? Further, membrane constituents are also negatively charged, in the form phospholipids. Putative cis-charge repulsion represents an obstacle to the emergency of multicellularity. This is compounded by the fact that

Recognition of substrates by membrane potential of immobilized enzyme membranes: membrane potential theory

Journal of the Chemical Society, Faraday Transactions, 1991
The shifts in membrane potential, caused by the injection of D-glucose into a permeation cell, were obtained theoretically from membrane potential theory and compared to experimental data measured for immobilized (entrapped) glucose oxidase membrane and its lamellar enzyme membranes.
