Why is facilitated diffusion necessary.

Feb 2, 2023 · Facilitated diffusion is a spontaneous process in which charged ions or molecules are transported across the lipid-based cell membrane via a carrier transmembrane protein molecule. It is a selective process, which means the membrane allows only selective molecules and ions to pass through it, denying passage to others.
