Question

Explain facilitated diffusion. Where is this happening in the cell? Is the substance moving up or down a concentration gradient? When will this process stop?

Answer 1

Step-by-step explanation:

Facilitated diffusion is diffusion with the help of carrier proteins, it occurs at the cell membrane. The substance is moving down the concentration gradient, from high concentration to low concentration. This will stop once the inside of the cell and the outside of the cell have reached equilibrium.
