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 + O2
The 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 else can I help you with?
What is the chemical reaction called where water is removed during the reaction?
This chemical reaction is called dehydration.
What are the materials you have at the beginning of a chemical reaction called?
The starting materials in a chemical reaction are called reactants.
What are the ending materials in a chemical reaction called?
The ending materials in a chemical reaction are called products. These are the substances that are formed as a result of the chemical reaction taking place.
What are substance you start with in a chemical reaction called?
The reactants
What is an equation of chemical symbols and formulas that record the process of a chemical reaction called?
That is called a chemical equation. It represents the reactants, products, and their ratios in a chemical reaction.
What is the chemical reaction called where water is removed during the reaction?
This chemical reaction is called dehydration.
What is the starting substance in a chemical reaction is?
The substances you have at the beginning of a chemical reaction are called the reactants.
What are the materials you have at the beginning of a chemical reaction called?
The starting materials in a chemical reaction are called reactants.
What chemical is formed in a chemical reaction?
A new chemical substance is formed during a chemical reaction by rearranging the atoms of the reactants. The products of a chemical reaction have different properties compared to the original reactants.
What is a substance that is changed in a chemical reaction Called?
A substance that undergoes change in a chemical reaction is called a reactant.
Is the substances formed in a chemical reaction are called reactants?
Substances formed in a chemical reaction are called products.
What are the ending materials in a chemical reaction called?
The ending materials in a chemical reaction are called products. These are the substances that are formed as a result of the chemical reaction taking place.
What are substance you start with in a chemical reaction called?
The reactants
What is molecules which serve as chemical to make reactions work?
Molecules or compounds that function to allow a reaction to take place but do NOT take place in the reaction itself are called catalysts. Biological catalysts made of proteins are called enzymes.
What chemical reaction produces heat and energy in a star?
it is not a chemical reaction. It is a nuclear reaction and it is called fusion.
What is chemical reaction of oxygen with other substances called?
The chemical reaction of oxygen with other substances is called oxidation.
What is an equation of chemical symbols and formulas that record the process of a chemical reaction called?
That is called a chemical equation. It represents the reactants, products, and their ratios in a chemical reaction.
