The peroxidatic function of the liver is the function that creates hydrogen peroxide.
When Hydrogen Peroxide (2H2O2) is combined with a small piece of liver, the hydrogen peroxide decomposes. This is because the small piece of liver acts as a catalyst, or the cause, of the decomposition of the Hydrogen Peroxide.The balanced equation is thus:2H2O2 (Hydrogen Peroxide) ---------> 2H2O + O2
Hydrogen peroxide is an oxidising agent, and oxidation is an exothermic reaction. The liver is being oxidised.
The enzyme in the liver (catalase) decomposes the hydrogen peroxide (H2O2) into water and oxygen molecules.
Catalase is the protein that catalyzes the decomposition of Hydrogen Peroxide to diatomic Hydrogen and Oxygen. Heat denatures or destroys proteins, so a boiled liver sample has denatured catalase proteins which can no longer perform their metabolic function.
You can decompose hydrogen peroxide into water by adding a few pieces of uncooked diced potato or liver to it. Both potatoes and liver contain enzymes that will break down hydrogen peroxide.
Enzymes in the liver.
test it and find out
The enzyme catalase breaks down hydrogen peroxide in the liver. Seasons do not generally affect the amount of hydrogen peroxide breakdown, because humans regulate their body temperature.
Catalase, however it does not produce hydrogen peroxide but rather catalyzes the breakdown of hydrogen peroxide into water and oxygen gas.
Colourless, oxygen is produce by the catalytic action of the Iron in the liver on the hydrogen peroxide. 2 H2O2 -> 2 H2O + O2.
By macerating the liver, you are increasing its surface area (SA) therefore, the enzyme catalase can break down the hydrogen peroxide at a much faster and easier rate.
It reacts more quickly than uncrushed liver would. This is because more catalase is exposed to the hydrogen peroxide.
