Heat and pH dependence of catalase. A comparative study

WebNov 22, 2024 · To examine the effects of environmental changes on enzymatic activity, we will work with the enzyme catalase. This is a very common enzyme that is present in most living organisms. Catalase catalyzes the breakdown of hydrogen peroxide to water and oxygen: 2 H 2 O 2 → 2 H 2 O + O 2. We will measure catalase activity somewhat indirectly. WebElina Levina; TA: Eilea Knotts Catalase Enzyme Activity Abstract The human body utilizes catalase enzymes to break down hydrogen peroxide (Gaetani et al, 1994). This catalase enzyme system is important because it gets rids of toxins in hydrogen peroxide the body does not need and at a moderate rate (Kampshmidt, 1965). irish keychain https://radiantintegrated.com
