WebA membrane that has selective permeability allows only substances meeting certain criteria to pass through it unaided. In the case of the cell membrane, only relatively small, nonpolar materials can move through the lipid bilayer (remember, the lipid tails of the membrane are nonpolar). WebThe transport and permeability characteristics of the luminal and basolateral membranes are not the same due to the presence of different ion channels and transporters. Substances, therefore, are able to move …
