What is the effect of concentration of H2O2 on the rate of catalase activity? Aim: - This is an experiment to examine how the concentration of the substrate hydrogen peroxide (H2O2) affects the rate of reaction of the enzyme catalase. Preliminary: - Enzymes such as catalase are proteins. They are specific to a certain shape and are used to speed up a certain reaction. They do not run out for they are not used up. Catalase is a catalyst. Catalase is an enzyme found in food such as potato and liver. It is manufactured by cells to break down H2O2 (hydrogen peroxide) a poisonous bi-product of metabolism. Catalase speeds up the decomposition of hydrogen peroxide into water and oxygen as shown in the equation below. catalase 2H2O2 ???? 2 H2O + O2 hydrogen water oxygen peroxide It is able to speed up the decomposition of hydrogen peroxide because the shape of...
