Effect of Temperature on Peroxidase Ability 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

So most people rely on deicers such as salt because it does a great job melting ice‚ but it also damages concrete surfaces over time. How does salt damage concrete surfaces? Salt lowers the pH balance in the concrete. Because it is acidic‚ it weakens the strength of the concrete and increases the sizes of the pores. This allows water and other elements to penetrate the surface. Salt also attracts and retains

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
