(a) Carrier molecules or carrier proteins involved in facilitated diffusion, facilitate the diffusion of hydrophilic substances through biological membrane. They are specific and allow the cells to select solute of an appropriate size to be transported. Carrier proteins can increase the rate of diffusion and may undergo change upon binding to solutes |
