Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
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.
Correct Answer: B
Solution :
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.
