Solution

The correct option is C Assertion is correct but Reason is incorrect

Enzymes act as catalysts, substances that accelerate the rate of a chemical reaction, by reducing the activation energy necessary to initiate the reaction. They are not altered in reaction and the same enzyme molecule can be used over and over, only small quantities of enzymes are needed in the cell.

So the correct answer is option C.
