(Facilitated Diffusion), Carrier protein.

In facilitated diffusion, the carrier protein facilitate the molecule by changing its shape and move the molecule across the membrane. Since that facilitated diffusion is a passive transport, it does not require ATP. BUT, how can the shape of the carrier protein changes since that it does not have a...
