Beauty · Answer 1

Enzyme shows increased activity up to a certain temperature.

Explanation:

Enzymes are organic catalysts which are protein in nature hence they are sensitive to changes in temperature. They work best only within a narrow range of temperature between 35-40°c. As the temperature increases, the optimum temperature is reached. Above the optimum temperature, the rate of reaction decreases sharply because higher temperatures denatures enzymes thus inactivating them.

Stephany Barnes · Answer 2

Answer: C) The enzyme shows increased activity up to a certain temperature.

Explanation:

The kinetic energy of the molecules increases with a rise in temperature. So the enzyme shows increased activity up to a certain temperature.
