NEETBotanyBiomolecules (B)
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Dehydrogenases are enzymes which catalyse oxidoreduction between two substrates. Reason (R): Transferases are enzymes catalysing a transfer of a group, other than hydrogen, between a pair of substrates. In the light of the above statements, choose the most appropriate answer from the options given
Options
- ABoth Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A)
- BBoth Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A)
- CAssertion (A) is true but Reason (R) is false
- 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 dehydrogenases (also known as oxidoreductases) are the class of enzymes which catalyse oxidoreduction between two substrates. Reason (R) is true because transferases specifically catalyse the transfer of a group, other than hydrogen, between a pair of substrates. Both statements are factually correct according to the standard IUBMB classification of enzymes, but Reason (R) is not the correct explanation for Assertion (A). The correct explanation for Assertion (A) would relate to the me
