Why can't insulin be given orally to diabetic patients?
Show Hint
Insulin = Protein. Proteins get digested.
Updated On: Oct 10, 2025
- It will be digested in Gastro-Intestinal (GI) tract.
- Because of structural variation.
- Its bioavailability will be increased.
- Human body will elicit strong immune response.

The Correct Option is A
Solution and Explanation
Insulin is a protein hormone. If taken orally, it would be broken down by digestive enzymes in the stomach and small intestine, rendering it ineffective. This is why insulin is typically administered by injection, allowing it to enter the bloodstream directly.

- The plates of a parallel plate capacitor are separated by d. Two slabs of different dielectric constant \(K_1\) and \(K_2\) with thickness \(d/2\) and \(d/2\) respectively are inserted in the capacitor. Due to this, the capacitance becomes two times larger than when there is nothing between the plates. If \(K_1 = 1.25 K_2\), the value of \(K_2\) is :

- Consider the diameter of a spherical object being measured with the help of a Vernier Callipers. Suppose its 10 Vernier Scale Divisions (V.S.D.) are equal to its 9 Main Scale Divisions (M.S.D.). The least count in the M.S. is 0.1 cm and the zero of V.S. is at -0.1 cm when the jaws of Vernier callipers are closed. If the main scale reading for the diameter is \(M = 5\) cm and the number of coinciding vernier division is 8, the measured diameter after zero error correction, is:
