The usual substrate for the pancreatic enzyme peptidase is

• A. Starch
• B. Cellulose
• C. Glucose
• D. Peptides

Answer: (D)

Pancreatic peptidases hydrolyze peptide bonds, so their usual substrate is peptides. They act on peptide chains derived from dietary proteins, breaking them down into smaller peptides and amino acids for absorption. Carbohydrates are handled by pancreatic amylase (starch), and cellulose isn’t digested by human pancreatic enzymes, while glucose is a product of carbohydrate digestion rather than a substrate for proteases.
