The villi can increase the surface area in the small intestine for absorption of digested food. As the villi has a thin wall, one cell thick, which can speed up diffusion, and a network of blood capillaries to absorb and transfer nutrients.
And in large intestine, those folds can also increase the surface area for reabsorption of unabsorbed food, mostly water.
Transport proteins multi-pass so that multiple alpha helices can form a hydrophilic pore that is able to diffuse small molecules. If transport proteins were single-passing, the alpha helix would not have a core with a diameter large enough to diffuse solutes.
Multi-pass membrane proteins loop in and out, while single-pass membrane proteins cross the membrane once.
Answer:
A pairs to T. & G pairs to C
