    Because of structural variation
  2. B

  3. C

  4. D
    It will be digested in Gastro-Intestinal (GI) tract
View written solutionFree

Correct answer: D

Insulin is a peptide hormone, so if taken by mouth:

It passes through the stomach’s acidic environment

Proteolytic enzymes in the GI tract break its peptide bonds

Practically none of the intact hormone reaches the bloodstream

Therefore the correct choice is Option D: It will be digested in the Gastro-Intestinal tract.
