WebFortunately peroxisomes produce copious amounts of the enzyme catalase and this helps break down hydrogen peroxide to water and oxygen. Peroxisomes are major users of oxygen and the oxygen produced from hydrogen peroxide is used within the organelle. One peroxisomal protein is involved in preventing excess quantities of the chemical … WebCatalase. Catalase performs its rapid destruction of hydrogen peroxide in two steps. First, a molecule of hydrogen peroxide binds and is broken apart. One oxygen atom is extracted and attached to the iron atom, and …
