_______________ have a single or multiple solute binding pockets and after solute binding, a reversible conformation movement exposes the solute-binding pocket to the other face of the membrane. - transporters Because of the factors affecting diffusion, H2O will move from an area of higher concentration (low osmolarity) to an area of lower concentration (higher osmolarity) if the cell membrane is permeable to H2O [6.03]. The movement of H2O in this way is a very powerful force, capable of r...
