Detailed explanation-1: -The enzyme known as ‘catalase’ is involved in the breakdown of hydrogen peroxide molecules into separate water and oxygen molecules. During this reaction, what happens to the ‘catalase’? The enzyme would be fully used up and discarded. The enzyme would remain unchanged in any way.
Detailed explanation-2: -When the enzyme catalase comes into contact with its substrate, hydrogen peroxide, it starts breaking it down into water and oxygen.
Detailed explanation-3: -Catalase enzymes break down hydrogen peroxide (H2O2) to water and oxygen molecules, which protects cells from oxidative damage by reactive oxygen species. Commercial catalases are produced from Aspergillus niger through a solid-state fermentation process (Fiedurek and Gromada, 2000).
Detailed explanation-4: -As previously mentioned, it is well established that catalase possesses an activity responsible for degrading hydrogen peroxide via the reaction: 2H2O2 → 2H2O + O2.
Detailed explanation-5: -Catalase is a heme containing enzyme which catalyses the breakdown of hydrogen peroxide to water and molecular oxygen.
