WHEN catalase is added to hydrogen peroxide, there is an initial rapid evolution of oxygen which lasts for about two minutes, depending on the peroxide concentration. After this, oxygen is given off at a steady rate which slowly decreases in the course of an hour.
The catalase enzyme causes the hydrogen peroxide to break down. This reaction forms water and oxygen. The bubbles are oxygen gas.
