| Many of these enzymes, such as catalase and glutathione peroxidase, are constitutively active and protect the lungs against everyday insults. |
| The most simple case of such a chemical reaction is the decomposition of hydrogen peroxide in the presence of the enzyme catalase inside the cell. |
| However, it has been noticed that some of these chemicals, including amitrole, can also inhibit the activity of the peroxisomal catalase. |
| In the case of Gram positive cocci, we did a catalase test followed by, for example, a coagulase test or an optochine test. |
| In addition, normal cell growth could be restored by addition of catalase to the medium, breaking down the hydrogen peroxide to oxygen and water. |
| This enzyme uses inorganic oxygen as an electron acceptor and H 2 O 2 is formed that has to be detoxified by a catalase. |
