Re: (Facilitated Diffusion), Carrier protein.

... low transition energy barrier. If the energy barrier between protein conformations is low, a protein can randomly pick up cargo on one side of the membrane and (THWACK with a solvent molecule) change conformation to release the cargo on the other side. Occasionally a cargo molecule will be moved ...
