Proteins determine most of the  membrane’s specific functions. There are two populations of membrane  proteins. Peripheral proteins  - not embedded in the  lipid bilayer - they are loosely bounded to the  surface of the membrane Plasma Membrane  Plasma Membrane  Proteins Proteins

Move the solute-binding site and solute across the  membrane as the protein changes shape. Shape changes could be triggered by the binding and  release of the transported molecule. Carrier Proteins
