Catalase is an enzyme that turns hydrogen peroxide into water and oxygen. A student fillsseven test tubes with equal amounts of catalase and 5 mL of hydrogen peroxide at differenttemperatures. The student records the number of bubbles produced in each test tube in agraph .What can the student correctly conclude from the graph?A. The structure and function of the enzyme remain intact at 60°C. B. The structure and function of the enzyme change at 30°C. C. The enzyme works best when the temperature is 40°C. D. The enzyme works best when the temperature is 0°C.6. The graphs show the rate of reaction vs. temperature and the rate of reaction vs. pHfor an enzyme. Which statement provides the correct interpretation of the graphs?

A. The enzyme works at a high level no matter how the temperature or pH changes.

B. The enzyme works best at a certain temperature and is not affected by changes in pH.
C. The enzyme works best at a certain pH and is not affected by changes in temperature.
D. The enzyme works at a high level within specific ranges of temperature and pH.
