Deltoid muscle _____ 2. into facilitated diffusion Why no energy is spent on switching the carrier proteins? For example: 7*x^2. In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. Membrane transport is dependent upon the permeability of the membrane, transmembrane solute concentration, and the size and charge of the solute. First, it is happening thanks to the concentration gradient. Before we can use the molecules we eat, they have to enter our cells, starting with the cells lining the small intestine.
