Catalase is an enzyme that breaks down hydrogen peroxide that is produced by the cell's metabolism into water and hydrogen peroxide.
Explanation:
Catalase is an enzyme that breaks down hydrogen peroxide into oxygen and water.
The video shows the decomposition of hydrogen peroxide catalyzed by catalse enzyme from liver.
Hydrogen peroxide is produced during certain chemical reactions in the cell, and is highly toxic to the cell. As an enzyme, catalase has an active site into which the substrate hydrogen peroxide will fit. The enzyme then catalyzes the breakdown of the substrate hydrogen peroxide into harmless oxygen and water and is free to react with another molecule of hydrogen peroxide.
