IN a recent communication in Nature 1, Dr. P. George described manometric experiments which showed a rapid initial decay of the enzyme compared with which the well-known decay due to irreversible ...

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 a ubiquitous enzyme found in nearly all living organisms, from bacteria to humans. Its primary function is to decompose hydrogen peroxide, a byproduct of metabolic reactions, into water ...

Thousands of different chemical reactions must happen inside ... and the substances produced are called products. In this example, the enzyme catalase acts on the substrate hydrogen peroxide ...

For example, in liver cells the toxic chemical hydrogen peroxide must be broken down into the harmless products, water and oxygen. If this reaction ... produce the enzyme catalase to speed up ...
