Question:
Assertion (A): Insulin can't be administered orally.
Reason (R): The animal insulin causes side effects to man due to non-self antigens.
Assertion (A): Insulin can't be administered orally.
Reason (R): The animal insulin causes side effects to man due to non-self antigens.
Show Hint
Insulin must be injected because the stomach would digest it as food.

- Both (A) and (R) are true. (R) is correct explanation for (A)
- Both (A) and (R) are true. (R) is not correct explanation for (A)
- (A) is true. But (R) is false
- (A) is false. But (R) is true
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Insulin therapy.
Step 2: Meaning
Why insulin requires injection and the historical issues with animal insulin.
Step 3: Analysis
Insulin is a protein, so it is digested if taken orally (A is true). Animal insulin can cause immunogenic reactions in humans (R is true). However, animal insulin's antigenicity is not the reason it cannot be taken orally; digestive enzymes are.
Step 4: Conclusion
Both are true, but R does not explain A.
Final Answer: (B)
