Vedclass · Answer

(C) Insulin is a peptide hormone composed of amino acids. Because it is a proteinaceous hormone,it cannot be administered orally as it would be digested by the proteolytic enzymes in the gastrointestinal tract. Furthermore,insulin is not lipid-soluble; it acts by binding to specific receptors on the surface of the cell membrane,as it cannot cross the lipid bilayer directly. Therefore,the Assertion is correct,but the Reason is incorrect.

$A$ : Insulin is not given orally.
$R$ : Insulin hormone is lipid soluble and directly enters inside the cell membrane.
