| facilitated diffusion | <physiology> A process by which substances are conveyed across cell membranes faster than would be possible by diffusion alone. This is generally achieved by proteins that provide a hydrophilic environment for polar molecules throughout their passage through the plasma membrane, acting as either shuttles or pores. See: symport, antiport, uniport. (18 Nov 1997) |

| facilitated transport | The protein-mediated transport of a compound across a biomembrane that is not ion-driven; a saturable transport system. Synonym: passive transport. (05 Mar 2000) |
| facilitated diffusion |
diffusion in which a substance not soluble by itself in lipids is transported across a selectively permeable membrane by combining with a transporter (carrier) molecule

| facilitated d. |
diffusion across a plasma membrane or other biological membrane in which the molecules to be transported form complexes with specific transport proteins (uniporters) that shuttle them across the membrane and release them on the other side; movement along the concentration gradient is downward. Called also uniport.
