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

H2O2 (hydrogen peroxide) is a naturally occurring compound that can be degraded by enzyme catalase. This is the overall chemical reaction that occurs when hydrogen peroxide is broken down in the presence enzyme catalase. 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). Reaction of hydrogen peroxide with catalase is two-step. 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). In this reaction, the enzyme catalase is a catalyst. This means that the enzyme catalase accelerates the reaction while not being consumed. While the first step (oxidation by hydrogen peroxide molecules) of the reaction is exothermic, the second is endothermic. Cont….
