How does catalase help the body?

Answer 1

Detoxification is one of the liver's functions. Catalase catalyses the breakdown of Hydrogen Peroxide which is toxic (It's highly reactive so can cause cell damage. It comes from the small intestine via the portal vein, from things we eat or drink, e.g. alcohol) to oxygen and water, which are harmless.

Answer 2

Functions of catalaseis a common enzyme found in nearly all living organisms that are exposed to oxygen where it functions to catalyze the decomposition of hydrogen peroxide to water and oxygen.

Catalase (H202:H202o xidoreductase, EC 1.11.1.6) is

of historical interest for having been the subject of

some of the earliest investigations of enzymes. A feature

of catalase that has been poorly understood for

several decades, however, is the mechanism by which

catalase remainsa ctive in the presence oift s own substrate,

hydrogen peroxide. They reported recently that

catalase contains tightly bound NADPH. The present

study with bovine and human catalase revealed that

NADPH both prevents and reverses the accumulation

of compound 11, an inactive form of catalase that is

generated slowly when catalaseis exposed to hydrogen

peroxide. Since the effect of NADPH occurs even at

NADPH concentrations below 0.1 g ~ t,he protective

mechanism is likely to operate in vivo

Answer 3

Catalase is essential for all life as it breaks down hydrogen peroxide, which is a product of respiration sometimes. As it is toxic, it must be broken down rapidly. Catalase decomposes hydrogen peroxide into water and oxygen, which is safe. It is the fastest enzyme known to man, and it needs to be (for obvious reasons).

Answer 4

To prevent the accumulation toxic levels of hydrogen peroxide.

Answer 5

Catalase is an enzyme that speeds up the decomposition of hydrogen peroxide into water and oxygen.

Answer 6

It helps break down catalose.
