What appears to be the effect of inserting a protein channel into the membrane on themovement of molecules across the membrane?11. Is the inner surface (facing the channel) of the embedded protein likely to be polar or nonpolarin the examples shown in Model 4? Is the exterior surface (facing the fatty acid chains of thephospholipids) 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 thedirection down their concentration gradient (from high concentration to low concentration) it iscalled facilitated diffusion. Transport proteins may also be involved in active transport where thecell uses energy from ATP to move molecules across a membrane against or up their concentrationgradient.Extracellular Fluid w<Cytoplasmic Fluidx
