What is facilitated diffusion?

1 Answer

Facilitated diffusion is a type of passive transport that moves particles through channel proteins.


Facilitated diffusion is the movement of particles from an area of high concentration to an area of low concentration.

The particles cannot move directly through the membrane, so they move through channel proteins which function like doorways in the cell membrane.
