Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Amylase is an enzyme that helps in the digestion of starch into smaller carbohydrate molecules. Reason (R): Starch is a polymeric carbohydrate consisting of glucose monomers linked together by glycosidic bonds. In the light of the above statements, choose the correct answer from the options given b

Options

  1. ABoth Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A)
  2. BBoth Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A)
  3. CAssertion (A) is true but Reason (R) is false
  4. DAssertion (A) is false but Reason (R) is true

Correct answer

B. Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A)

Step-by-step solution

Assertion (A) is true because amylase is the enzyme responsible for the hydrolysis of starch into smaller carbohydrates like maltose. Reason (R) is also true because starch is a homopolymer of glucose where the monomers are linked by glycosidic bonds. However, Reason (R) merely describes the structural composition of starch. It does not explain why amylase digests it; the explanation for the Assertion is the specific active site of amylase that catalyses the cleavage of glycosidic bonds. Therefore, both (A) and (R)
