Example of Facilitative Diffusion. In the cell, examples of molecules that must use facilitated diffusion to move in and out of the cell membrane are glucose, sodium ions, and potassium ions. They pass using carrier proteins through the cell membrane without energy along the concentration gradient.acilitated diffusion does not require energy and occurs along the concentration gradient. The concentration gradient is the process of particles moving/diffusing from an area of higher concentration to an area of lower concentration.
