PRINCIPLE: The breakdown of hydrogen peroxide into oxygen and water is mediated by the enzyme catalase. When a small amount of an organism that produces catalase is introduced into hydrogen peroxide, rapid elaboration of bubbles of oxygen, the gaseous product of the enzyme's activity is produced.RINCIPLE: The breakdown of hydrogen peroxide into oxygen and water is mediated by the enzyme catalase.
