Question

Optimum temperature is the temperature at which an enzyme

• A. Works at its best
• B. Is not destroyed
• C. Action is reversed
• D. Is inactivated

Answer 1

The correct option is A Works at its best

Enzymes are made up of proteins which accelerates the rate of the reaction. It lowers the activation energy and converts the reactants into substrate. The increased temperature increases the kinetic energy of the enzymes which further accelerates the activity of the enzyme but at higher temperature it gets denatured as the peptide bonds between the proteins molecules breaks which disrupts the structure of enzymes. It requires an optimum temperature for its activation. High temperature denatures the enzyme and low temperature deactivates the enzyme.

So, the correct answer is option A.
