This formula reveals that two hydrogen atoms (H) and two oxygen atoms (O) make up hydrogen peroxide. It foams is because ...

Science presenter Jon Chase demonstrates the action of the enzyme catalase, produced by the liver, in breaking down hydrogen peroxide into water and oxygen. The balanced equation for this reaction ...

Liver cells produce the enzyme catalase to speed up the breakdown of hydrogen peroxide. Enzymes can speed up the break down of complex molecules into simpler molecules or the building up of simple ...
