5. What did measuring the bubble column heights in all the experimental procedures indicate? 6. What purpose did the tube containing water and hydrogen peroxide serve in the catalase activity experimental procedure?

5. Measuring the bubble column heights in all the experimental procedures indicated the rate of reaction or the efficiency of the reaction. By measuring the height of the bubble column, we can determine how quickly the reaction is occurring and how much product is being formed. 6. The tube containing water and hydrogen peroxide served as a control in the catalase activity experimental procedure. It was used to compare the reaction rate of the catalase enzyme in the presence of hydrogen peroxide to the reaction rate in the absence of the enzyme. This control tube helps in determining the effect of the catalase enzyme on the reaction rate.
