Question

Difference between passive diffusion and facilitat

Answer 1

Answer:

Passive transport moves across a concentration gradient, or a gradual difference in solute concentration between two areas. ... Facilitated diffusion is diffusion using carrier or channel proteins in the cell membrane that assist in the movement of molecules across a concentration gradient.

Answer 2

In simple diffusion, the movement of particles occurs along the direction of the concentration gradient. In facilitated diffusion, the movement of molecules can occur both in direction and opposite of the concentration gradient.
