In mammals, most nutrient molecules are absorbed in the a) Stomach b) Liver c) Small intestine d) Large intestine e) Pancreas 3. Mammalian digestive enzymes are capable of digesting which of the following dietary molecules: a) cellulose b) amylopectin c) chitin d) polypeptides e) b &d f) all of the above 4. In the vertebrate midgut, fatty acids are transported across the apical membrane; once in the enterocyte they are then combined with subsequently secreted into the interstitial space by . to make TAG, forming chylomicrons, and a) fructose, passive transport b) glycerol, exocytosis. c) fructose, ATP d) ATP, facilitated diffusion e) NADH, cotransport 5.
