In the small intestine, protein digestion continues due to which enzymes?

• A. Salivary amylase
• B. Pancreatic enzymes
• C. Bile
• D. Pepsin

Answer: (B)

In the small intestine, protein digestion continues due to pancreatic proteases. The pancreas releases enzymes like trypsin, chymotrypsin, and carboxypeptidases in the form of inactive zymogens, which are activated in the duodenum by enterpeptidase. Once active, these enzymes cut peptide bonds to yield smaller peptides and amino acids, which are then further processed by enzymes on the intestinal lining to be absorbed. Salivary amylase targets carbohydrates, not proteins. Bile helps with fat digestion, not protein breakdown. Pepsin works in the stomach's acidic environment and is not active in the small intestine, where digestion proceeds mainly with pancreatic enzymes.
