studying the effect of pH on catalase activity. Catalase by scavenging hydrogen peroxide to water and oxygen is an important enzyme of cell defense mechanisms against oxidative stress in all living organisms (Dat et al.‚ 2003). Cells use catalase because it is the most efficient enzyme as an antioxidative enzyme which lowers hydrogen peroxide or superoxide to accumulate to toxic levels in plant growth (Bowler et al. 1992). The formula that involves catalase as the enzyme is . pH is a measure of the

Lab on pH Levels Purpose: Throughout this experiment we are trying to learn how to take proper pH measurements using a pH meter. We also want to see the pH of different common liquids and record the change in pH when we add acids and alkaline liquids. The last reason we are conducting this experiment is to explain and show how fresh milk spoils by the change in pH. Materials: In this experiment we used graduated cylinders and glass beakers and added variety of ingredients including 50 mL of; soda

pH Affecting on Amylase Enzyme Is there a difference in the concentration of pH in the amylase enzyme activity? The null hypothesis would be that there will be no difference in the concentration of pH and alternative hypothesis would be that there will be a difference in the concentration of pH. The predication if that there will be a difference in the concentration of pH. The pH affects on enzyme activities‚ one of the enzyme that was used in the process was amylase.
