c) Only carbohydrate absorption involves digestion via brush border enzymes.

d) Only protein absorption involves facilitated diffusion transporters that allow the digested monomers to enter the interstitial fluid across the basolateral membranes of gut epithelial cells.

e) Only during protein absorption are digested monomers packaged into vesicles and secreted into the interstitial fluid across the basolateral membrane of gut epithelial cells
