Show ExplanationHide Explanation

Explanation

The matching is 1–B, 2–A, 3–C, 4–D. Salivary amylase hydrolyses starch; pepsin digests proteins in the stomach; trypsin cleaves proteins and peptides in the small intestine. Lipases hydrolyse fats: the principal products of pancreatic triglyceride digestion are free fatty acids and monoacylglycerols, with further hydrolysis capable of yielding glycerol.
