make up hydrogen peroxide. It foams is because blood and cells contain an enzyme called catalase. Since a cut or scrape ...

Strategies tested in mice include the use of nanomedicine or hydrogels loaded with catalase — an enzyme that breaks down hydrogen peroxide to water and oxygen — to decompose hydrogen peroxide ...

Liver cells produce the enzyme catalase to speed up the breakdown of hydrogen peroxide. The chemicals that enzymes act on are called substrates and the substances produced are called products.

Liver cells produce the enzyme catalase to speed up the breakdown of hydrogen peroxide. The chemicals that enzymes act on are called substrates and the substances produced are called products.

The cells in our hair bulb produce a little bit of hydrogen peroxide, which is a metabolic byproduct, and typically there's an enzyme called catalase that breaks this down to water and oxygen.
