The Chemical Reaction of Hydrogen Peroxide’s Breakdown in the Presence and Activity of Enzyme Catalase

The enzyme catalase can break down hydrogen peroxide (H2O2), a natural molecule. In the presence of enzyme catalase, the chemical reaction is called 2H2O2? 2H2O + O2. By reducing the activation energy, the enzyme catalase aids in this process. Catalase, a strong oxidizing agent responsible for the reduction of hydrogen peroxide to oxygen and water (Gul and al., 2016). It is a two-step reaction between catalase and hydrogen peroxide. First, the enzyme catalase is oxidized by hydrogen peroxide molecules. The second step involves the reduction of hydrogen peroxide into water and oxygen (Babic & Kaur, 2002). This is because the enzyme catalase serves as a catalyst for the reaction. It accelerates it but does not consume the product. While the reaction of enzyme catalase to hydrogen peroxide by the hydrogen molecule is exothermic, the second stage of the reaction (hydrogenperoxide breakdown), is endothermic. Cont….
