Facilitated diffusion

Facilitated diffusion, (facilitated transport) is a process of diffusion, a form of passive transport, via which molecules diffuse across membranes, with the assistance of transport proteins.

Facilitated diffusion involves the use of a protein to facilitate the movement of molecules across the membrane. In some cases, molecules pass through channels within the protein.
