Which one of the following is not a digestive enzyme in the human systems?

Trypsin

Gastrin

Correct Answer: Option B

Explanation

1. Digestive enzymes are proteins that break down food into smaller molecules. 2. Trypsin is a key protease (an enzyme that digests protein) produced by the pancreas. 3. Gastrin is a hormone, not a digestive enzyme. It is produced by G cells in the stomach lining and stimulates the secretion of gastric acid (hydrochloric acid) by the parietal cells of the stomach. While involved in digestion, it doesn't directly break down food components like an enzyme.
