GK QUESTION#3809
Match the following enzymes with their functions in the human digestive system.
Read each row across both columns.
| Enzyme | Function |
|---|---|
| 1. Salivary amylase | A. Breaks down proteins into peptides |
| 2. Pepsin | B. Breaks down starch into maltose |
| 3. Lipase | C. Breaks down fats into fatty acids and glycerol |
| 4. Trypsin | D. Breaks down peptides into smaller peptides in the small intestine |
Show Answer
Answer
A. 1–B, 2–A, 3–C, 4–D
Show 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.
