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.
[2]. Facilitated diffusion is a form of passive transport that uses no energy for the transport of molecules and substances through the membranes of cells. It is largely aided by proteins that are an integral part of the membrane.2].
