What is the difference between diffusion and facilitated diffusion

Answer 1

what is the difference between diffusion and facilitated diffusion

Diffusion :

Diffusion is net movement of anything from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration.

facilitated diffusion:

Facilitated diffusion is a form of facilitated transport involving the passive movement of molecules along their concentration gradient, guided by the presence of another molecule – usually an integral membrane protein forming a pore or channel.
