_____membranes proteins are associated with the bilayer through interactions with other membrane component on the surface of the membrane. Net movement of particles from a region where they are more concentrated to a region where they are law concentrated is called Diffusion of water through a selectively permeable membrane down its own concentration gradient It called A solution with an equivalent concentration of water and hence the tame osmotic pressure as the fluid inside the cell is said to be...
