FACILITATED DIFFUSION

facilitated diffusion: translation

(= passive transport)

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.

facilitated diffusion: translation

Diffusion across the plasma membrane that is aided by a carrier.
