The difference between simple diffusion and facilitated diffusion is that facilitated diffusion the difference between simple diffusion and facilitated diffusion is that facilitated diffusion requires atp. moves materials from a higher to a lower concentration. moves materials from a lower to a higher concentration. does not require atp. requires transporter proteins.

Explanation:

As we know, the plamatic membrane has a selective permeability, which allows substances to enter and exit the cell to maintain the balance of the concentrations of these substances in the intra and extra cellular environment, allowing the maintenance of the cell homeostasis. This is allowed through transport mechanisms, among which, facilitated diffusion is part.

The facilitated diffusion is a passive transport, carried out by the cell without the use of energy, therefore, it does not require ATP. This transport is carried out through transport proteins present in the membrane that allows the substances to leave the place with the highest concentration to the place with the lowest concentration.
