WebIntegral proteins that act as channels or pumps work in one direction. Carbohydrates, attached to lipids or proteins, are also found on the exterior surface of the plasma membrane. These carbohydrate complexes help the cell bind substances that the cell needs in the extracellular fluid. Web3 de jan. de 2024 · Proteins mediating facilitated diffusion are of two kinds: carrier proteins and channel proteins. Carrier proteins allow solute transport. Ions, with their high charge-to-mass ratio, need help to cross the hydrophobic membrane barrier; this is the job of channel proteins that essentially serve as ion pores.
