Large molecules and wastes move through the membrane through protein channels.

WHAT IS FACILITATED DIFFUSION:

Facilitated diffusion is a kind of passive transport in which molecules move in and out of a cell via the aid of transport proteins. Facilitated diffusion is similar to simple diffusion in the sense that molecules move down the concentration gradient in both processes. They are however, different in the sense that facilitated diffusion needs the help of membrane proteins.Large molecules and wastes usually employ this method. The two membrane proteins include; channel proteins and carrier proteins.
