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.

Membrane potentials of differentiating enterocytes

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1982
A positional analysis of enterocyte membrane potential has been carried out using in vitro preparations of rabbit distal ileum. Young enterocytes were found to possess a microvillar membrane potential significantly less than that seen in older enterocytes.

Relationship of epithelial membrane potentials to corneal potential

Experimental Eye Research, 1973
Abstract The rabbit corneal potential arises as the sum of three steps across the epithelium. These occur across the squamous cell outer membrane, at the transition region between wing and basal cells, and across the basal cell inner membrane. Variations in corneal potential are inversely proportional to outer membrane potential.

Membrane potential, surface potential and ionic permeability

Physics Letters A, 1979
To clarify contributions to cellular transmembrane potential concentration potentials of phospholipid bilayer membranes and surface potentials of phospholipid monolayers were measured with respect to salt concentrations and various surface charge densities.

Quantitative Analysis of Membrane Potentials

2009
The changes that occur in electrochemical gradients across biological membranes provide us with invaluable information on physiological responses, pathophysiological processes and drug actions/toxicity. This chapter aims to provide researchers with sufficient information to carry out a quantitative assessment of mitochondrial energetics at a single ...
