What appears to be the effect of inserting a protein channel into the membrane on the movement of molecules across the membrane? 11. Is the inner surface (facing the channel) of the embedded protein likely to be polar or nonpolar in the examples shown in Model 4? Is the exterior surface (facing the fatty acid chains of the phospholipids) of the embedded protein likely to be polar or nonpolar? Explain your reasoning. When a membrane protein assists in the passive transport of molecules across a barrier in the direction down their concentration gradient (from high concentration to low concentration) it is called facilitated diffusion. Transport proteins may also be involved in active transport where the cell uses energy from…
