Which enzyme digests proteins?

Which enzyme digests proteins?

• A. Trypsin
• B. Lipase
• C. Amylase
• D. Protease

Answer: (A)

Enzymes that digest proteins are proteases that cleave peptide bonds in polypeptides. Among the options, lipase and amylase target fats and carbohydrates, respectively, leaving proteins untouched. The enzyme that specifically digests proteins is trypsin, a pancreatic protease activated in the small intestine that hydrolyzes peptide bonds, especially after lysine or arginine residues. Because it is the precise protein-digesting enzyme described, it is the best choice. The term protease refers to the broader family of protein-digesting enzymes, but the question asks for the particular enzyme, which is trypsin.
