THAT the catalytic decomposition of hydrogen peroxide by catalase requires the presence of molecular oxygen was demonstrated by a number of manometric experiments previously described 1.

Catalase is found in most cells ... Are your dishes looking dingy or extra dirty after a heavy meal? Add two ounces of hydrogen peroxide to your liquid dish detergent for an extra cleaning ...

Worth looking after it! Enzymes ... The active site of the catalase allows the hydrogen peroxide molecule to fit exactly. You could say the active site is like the ring of a bottle opener.

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.

After making a connection between ... the use of nanomedicine or hydrogels loaded with catalase — an enzyme that breaks down hydrogen peroxide to water and oxygen — to decompose hydrogen ...
