Hydrogen peroxide (H2O2) is a toxic chemical (waste product) that is produced when our bodies break down aminoacids and complete other important metabolic reactions. Catalase is an enzyme found in our livers that is responsiblefor the decomposition (break down) of hydrogen peroxide into the harmless compounds of water and oxygen. Dueto the enzyme's action, the cells in our bodies are able to rid themselves of the harmful H,O2 waste product. Withoutthe catalase enzyme, many of our cells would be damaged by the increased amount of H2O2. When the enzyme isworking, oxygen gas bubbles will be released. The chemical reaction that occurs is the following:catalase2H,O2→ 2H,O+O2Students in biology class performed an experiment to test the activity of catalase at different pH levels.
