Facilitated diffusion does NOT require energy. It is facilitated because of the help of a transport protein, but the molecules are still going down the concentration gradient. Facilitated diffusion does NOT require energy, as it is still going down the concentration gradient. diffusion does NOT require energy. diffusion is not a form of active transport.
Active transport is like facilitated diffusion, however, active transport requires energy from ATP, and moves materials against a concentration difference, from low to high concentration. Relevance to Class: In class, we have learned about simple diffusion, facilitated diffusion, and active transport. This video is helpful for anyone who needs more help distinguishing between simple diffusion, facilitated diffusion, and active transport.
