Question:
Which of the following statement is correct?
Which of the following statement is correct?
Show Hint
Remember which enzymes work in the acidic stomach and which hormone drives gastric secretion.
Updated On: Nov 12, 2026
- Pepsin acts on protein in acidic medium.
- Trypsin acts on protein in acidic medium.
- Pepsinogen is converted to pepsin by enterokinase.
- Release of gastric juice from stomach is stimulated by secretin.
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
Different digestive enzymes need different pH conditions and are activated by different agents.
Step 2: Check the statements
Pepsin works at about pH 2 in the stomach, so A is correct. Trypsin works in the alkaline small intestine, so B is wrong.
Step 3: Check activation and control
Pepsinogen is activated by HCl, while enterokinase activates trypsinogen, so C is wrong. Gastric juice is stimulated by gastrin, not secretin, so D is wrong.
Final Answer:
The correct statement is that pepsin acts on proteins in an acidic medium. \[ \boxed{\text{(A) }\text{Pepsin acts on protein in acidic medium.}} \]
