Figure 1 summarizes the permeability properties of pure lipid bilayers. Lipid-soluble molecules can readily pass through a lipid bilayer. Examples include gas molecules such as oxygen (O 2) and carbon dioxide (CO 2), steroid molecules, and fat-soluble vitamins (A, D, E, and K). Surprisingly, some small polar molecules are capable of permeating the lipid bilayer without the aid of a membrane transport protein.
Small molecules are able to move through gaps between the phospholipid molecules in membranes. What happens in Facilitated Diffusion They pass through carrier or channel proteins in the membrane, and their movement is facilitated by a protein. Molecules moving DOWN their concentration gradient. Which molecules pass through Simple Diffusion?
