Given below are two statements: Assertion (A): Human body is incapable of digesting cellulose. Reason (R): Starch degrading enzyme, diastase, is found in the human body. Choose the correct answer from the code given below:
- ABoth (A) and (R) are true and (R) is the correct explanation of (A).
- BBoth (A) and (R) are true but (R) is not the correct explanation of (A)
- C(A) is true but (R) is false
- D(A) is false but (R) is true
Show answer and explanation
Correct answer: (b) Both (A) and (R) are true but (R) is not the correct explanation of (A)
Explanation
Humans lack the enzyme to break the beta-glycosidic linkages of cellulose, so it passes undigested as dietary fibre – Assertion is true.
The enzyme diastase (amylase) does digest starch in the human body – Reason is also true.
But starch digestion does not explain the inability to digest cellulose, so (R) is not the correct explanation of (A).
