Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): In human beings, insulin is synthesized as a pro-hormone which needs to be processed before it becomes fully mature and functional. Reason (R): The extra stretch of C-peptide is to be removed from A and B peptide chain of insulin. In the light of the above statements, Choose the most appropriate answer from the option given below :
(A) is True but (R) is False.
(A) is False but (R) is True.
Both (A) and (R) are True and (R) is the correct explanation of (A).
Both (A) and (R) are True but (R) is not the correct explanation of (A).
In mammals, including humans, insulin is synthesised as a pro-hormone... which contains an extra stretch called the C peptide. This C peptide is not present in the mature insulin and is removed during maturation into insulin' . The Reason correctly explains that the processing required (Assertion) involves the removal of this specific C-peptide stretch to allow the hormone to become mature and functional.
