Question:
The proteolytic enzyme found in the gastric juice of infants which helps in the digestion of milk proteins is
The proteolytic enzyme found in the gastric juice of infants which helps in the digestion of milk proteins is
Show Hint
This enzyme curdles milk protein by changing caseinogen to casein.
Updated On: Nov 12, 2026
- Renin
- Rennin
- Salivary amylase
- Lysozyme
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
Infants drink milk, so their gastric juice has an enzyme that acts on milk protein.
Step 2: Recall the enzyme
Rennin (chymosin) converts caseinogen into casein, which forms a curd with calcium and stays longer in the stomach for pepsin to digest.
Step 3: Eliminate others
Renin of the kidney acts on angiotensinogen, salivary amylase digests starch and lysozyme kills bacteria.
Final Answer:
The enzyme is rennin. \[ \boxed{\text{(B) }\text{Rennin}} \]
