The Difference Between Simple Diffusion and Facilitated Diffusion is That

Question

The difference between simple diffusion and facilitated diffusion is that facilitated diffusion
A)moves materials from a higher to a lower concentration.
B)moves materials from a lower to a higher concentration.
C)requires ATP.
D)requires transporter proteins.
E)does not require ATP.

Accepted Answer

Facilitated diffusion requires transporter proteins to move materials across the cell membrane, while simple diffusion occurs spontaneously without the need for any special proteins. Additionally, facilitated diffusion does not require ATP, and moves materials from a higher to a lower concentration.
