Question

Assertion: Enzymes are proteins which catalyse biochemical reactions. Reason: The enzymes itself unchanged in the reaction, its presence allows the reaction to take place.

• A. If both Assertion and Reason are true and Reason is the correct explanation of Assertion.
• B. If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
• C. If Assertion is true but Reason is false.
• D. If both Assertion and Reason are false.

Answer 1

Answer: (B)

Enzyme is a biomolecule either protein or RNA (eg, Ribozyme) that catalyses a specific chemical reaction. It does not affect the equilibrium of the catalyzed reaction. It enhances the rate of a reaction by providing a reaction path with a lower activation energy. The enzyme itself remains unchanged after reaction.
