An enzyme is a substance that acts like a catalyst in living organisms , regulating the rate at which chemical actions proceed without itself being altered in the process. Simple answer from Google.

An enzyme is a protein that helps speed up a chemical reaction by lowering its activation energy.

  • Hydrogen peroxide is produced by an enzyme called peroxide dismutase, which catalyzes the dismutation of superoxide radicals (O2-) to oxygen (O2) and hydrogen peroxide (H2O2).

  • The cells then remove the excess of hydrogen peroxide (H2O2) by an enzyme called catalase.

  • If a cell couldn’t make catalase then it would not be able to catalyze the oxidation of different metabolites and toxins (e.g. formaldehyde, acetaldehyde, formic acid, etc).

  • H2O2 is broken down by catalase in order to form water (H2O) and molecular oxygen (O2).

In conclusion, catalase is a key enzyme that catalyzes the elimination of hydrogen peroxide (H2O2), forming water (H2O) and molecular oxygen (O2).
