Cell Membrane Introduction, Structure & Function
Biophysicists measuring the electric current passing through cell membranes have found that, in general, cell membranes have a vastly greater electrical conductance than does a membrane bilayer composed only of phospholipids and sterols. Web carrier proteins and channel proteins are the two major classes of membrane transport proteins. Web in contrast to the plasma membrane,.
Small Channels That Form Across The Plasma Membrane The resting potential is determined by concentration gradients of ions across the membrane and by membrane permeability to each type of ion. Some integral membrane proteins form a channel that allows ions or other small molecules to pass, as shown below.
