- 16. Describe the locations where chemical digestion begins and ends, and where nutrient absorption occurs, for the major classes of macronutrients by completing the paragraphs below. The chemical digestion of carbohydrate macromolecules begins in the X, where the enzyme Xis secreted by the salivary glands. Carbohydrate digestion is completed in theX by the enzyme X that was made in the X. The nutrients produced by the digestion of carbohydrates are called X and are absorbed in the X. The chemical digestion of protein macromolecules begins in the X, where the enzyme X is secreted. Protein digestion is completed in the X by enzymes made in the X. The nutrients produced by the digestion of proteins are called X and are absorbed in the X. The chemical digestion of lipid macromolecules begins in the X where the enzyme X is secreted. Bile is procuced by the X and stored in the X. Bile is secreted into the X where it emulsifies lipids. Lipid digestion is completed in the X by the enzyme X…342.
