    to Break Down H2O2 By: Rodneika Crutcher Abstract Temperature affects the ability of peroxidase to break down hydrogen peroxide. In this experiment our professor extracted peroxidase from potato tissue. In order to determine how temperature affects peroxidase we created solutions and measured their absorbance levels after water bath treatments. The more absorbent the solution was the less hydrogen peroxide there was in the solution. This means the peroxidase was able to break down the hydrogen peroxide

    How does temperature affect the rate of reaction for Lipase? As the temperature increases‚ so will the rate of enzyme reaction. However‚ as the temperature exceeds the optimum the rate of reaction will decrease. I predict that at temperatures above 70°C the enzyme lipase will become denatured and at temperatures below 10°C the enzyme will become inactive. Since lipase operates within the human body I’d also predict that its optimum temperature would be around human body temperature which is approximately
