Question

4. Assertion : HCl converts pepsinogen into active enzyme pepsin.

Reason : Pepsin converts protein into proteoses and peptones.​

Answer 1

Answer:

Correct option (b )Both A and R are correct and R is not the correct explanation of A. Explanation: Pepsin is a digestive enzyme that is released in stomach as proenzyme -pepsinogen. HCl which is secreted by gastric glands of stomach converts proenzyme pepsinogen into the active enzyme pepsin Pepsin converts proteins into proteoses and peptones.Read more on Sarthaks.com - https://www.sarthaks.com/234908/assertion-hcl-converts-pepsinogen-in-to-active-enzyme-pepsin

Answer 2

Assertion : HCl converts pepsinogen into active enzyme pepsin.

Reason : Pepsin converts protein into proteoses and peptones.

• Assertion and Reason are correct, but reason is not the correct explanation.

____________

Inside the stomach , acidic pH is achieved by secretion of HCl after food enters the stomach. This acidic environment converts Pepsinogen to Pepsin (active form).

Now, Pepsin is a protein digesting enzyme and it converts proteins into smaller particles called proteoses and peptones.

This is how protein digestion is initiated in the stomach.
