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.
Simple diffusion, on the other hand, is the passage of a molecule or ion in a membrane without the help or aid of another intermediary such as proteins. What drives the molecules and ions from a certain point to the other side of the membrane is through diffusionâs force.
