WebCell membranes are semi-permeable barrier separating the inner cellular environment from the outer cellular environment. Since the cell membrane is made up of a lipid bilayer with proteins attached on the surface and also passing through the cell membrane, there is possibility of transport across this membrane. WebCell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and...
