Solutions For 9780131905429 Chapter 2 Problem 10STP

Concentration of Catalase and amount of Oxygen given off

Catalase is an enzyme that acts as the catalyst to speed up the reaction involving the production of oxygen and water from the hydrogen peroxide. The rate of reaction will be zero in the absence of catalase enzyme. As the concentration of enzyme increases, the rate of reaction also increases. More is the concentration of enzyme, more the number of active sites available for the reaction. Higher the number of active sites, higher the amount of product formed. The rate of oxygen production will be highest at the highest enzyme concentration.

Hence, the correct answer is option (E) 20%.
