A: Facilitated diffusion differs from simple diffusion in that it crosses a membrane with the aid of passive transport proteins embedded in the membrane. Both types of diffusion are the movement of particles in solution from areas of higher concentration to areas of lower concentration.
Facilitated diffusion. Facilitated diffusion is a process whereby a substance passes through a membrane with a aid of an intermediary or a facilitator. The facilitator is an i ntegral membrane protein that spans the width of the membrane.The force that drives the molecule from one side of the membrane to the other is the force of diffusion.acilitated diffusion.
