Does liver contain an enzyme which breaks down H2o2?
H2O2 (Hydrogen Peroxide) is broken down by Catalase [an enzyme of the Peroxidase family], produced by every living animal cell. So yes.
What causes hydrogen peroxide to bubble?
The reason why it foams or bubble is because blood and cells contain an enzyme called catalase. Since a cut or scrape contains both blood and damaged cells, there is lots of catalase floating around. When the catalase comes in contact with hydrogen peroxide, it turns the hydrogen peroxide (H2O2) into water (H2O) and oxygen gas (O2). H2O2 --> H2O + O2 The reason why it foams or bubble is because blood and cells contain an enzyme called catalase.

What is the role of hydrogen in living organisms?
Oxygen burns hydrogen in the living system, releasing the energy that runs living beings.
What happens when you add hydrogen peroxide to liver and why?
What would happen to our cells if they made a poisonous chemical? You might think that they would die. In fact, our cells are always making poisonous chemicals. They do not die because our cells use enzymes to break down these poisonous chemicals into harmless substances. Enzymes are proteins that speed up the rate of reactions that would otherwise happen more slowly. The enzyme is not altered by the reaction. You have hundreds of different enzymes in each of your cells. Each of these enzymes is responsible for one particular reaction that occurs in the cell. In this lab, I am studying an enzyme that is found in the cells of many living tissues. The name of the enzyme is catalase; it speeds up a reaction, which breaks down hydrogen peroxide, a toxic chemical, into two harmless substances--water and oxygen. The reaction is as follows: 2H2O2 ----> 2H2O + O2 therefore there are enzymes in liver too
Is hydrogen a living organisms?
If you ment A living organism, then no it isn't. But I'm sure you ment in living organisms. Then yes, it is an important element found in most organisms and is used for a great range of functions. One example would be pH regulation in the blood, or any other liquid.
What is the job of the catalase enzyme?
Catalase breaks down toxic hydrogen peroxide in living organisms (in both plants and animals) into water and oxygen. 2H2O2 (reaction of catalase) produces 2H2O + O2
Why is catalase important for living organisms?
Catalase is an enzyme found in most organisms that are exposed to oxygen. It is important because it catalyzes the breakdown of hydrogen peroxide into oxygen and water. It mainly protects the cell from oxidative damage.
What is the purpose of a enzyme catalase in a living cell?
2H2O2 --> 2H2O + O2Catalyzing this reaction. The breakdown of hydrogen peroxide into water and oxygen gas.
Do animal cells have more catalase than plant cells?
Catalase is indeed found in all living things. It is a common enzyme that is found in tissue of organisms.

Is the poisonous hydrogen peroxide produced in the cells of living things converted into harmless materials by the action of enzyme catalase?

What function does catalase have?
to prevent the build up of hydrogen peroxideFunctions 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.
How does Hydrogen peroxide decomposes much faster in the presence of enzyme catalysts?
Try a peroxidase enzyme. For example "Versatile peroxidase", Jena Biosciences #EN-203L is an extremely effective catalyst.
What chemical reaction does the enzyme called catalse facilitate?
Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It catalyzes the decomposition of hydrogen peroxide to water and oxygen.It is a very important enzyme in reproductive reactions. Likewise, catalase has one of the highest turnover numbers of all enzymes; one catalase molecule can convert millions of molecules of hydrogen peroxide to water and oxygen each second.The reaction of catalase in the decomposition of living tissue:2H2O2 → 2H2O + O2The presence of catalase in a microbial or tissue sample can be tested by adding a volume of hydrogen peroxide and observing the reaction. The formation of bubbles, oxygen, indicates a positive result. This easy assay, which can be seen with the naked eye, without the aid of instruments, is possible because catalase has a very high specific activity, which produces a detectable response.
What causes hydrogen peroxide to bubble?

Does aloe vera contain catalase?
Apple does contain low amounts of the enzyme catalase. Fruits like cherries, kiwifruit, and pineapple have higher amounts of this enzyme. All living organisms contain this enzyme but in varying amounts.

Oxygen burns hydrogen in the living system, releasing the energy that runs living beings.
