Why does fresh liver react better in H2O2 then boiled liver?
It all has to do with catalase. Catalase is an enzyme and a biological catalyst in the decomposition of H2O2. When its fresh, catalase is still present in the liver. However, when the liver is boiled, the catalase enzyme is denatured (as it is a protein).
What is a food source of the enzyme catalase?
Carrots, patatoes, and liver are good sources of enzyme catalase
Why was liver used as a source of this enzyme?
liver is an organic compound that contains HIGH levels of catalase (enzyme)
What happens when you mix cold liver and peroxide?
The enzyme in the liver (catalase) decomposes the hydrogen peroxide (H2O2) into water and oxygen molecules. However this reaction will be slower then the liver being at 37 degrees celsius as this is the optimal condition for the enzyme catalase. The reaction will occur at a slower rate when an enzyme is below its optimal condition so generally when an enzyme is in cold conditions it will function slower.
What part of the body is catalase found?
In humans, Catalase exists in all the organs of the body, but is found mosty in the liver.
Why does frozen liver react with hydrogen peroxide more than raw liver?
the frozen liver reaction should have been slower than the liver at room temperature, as this is the optimal condition for the enzyme catalase. The reaction would occur at a slower rate when an enzyme is below its optimal condition so generally when an enzyme is in cold conditions it will function slower.
Mix hydrogen peroxide and liver?
The enzyme in the liver (catalase) decomposes the hydrogen peroxide (H2O2) into water and oxygen molecules.
Effect of pulping liver upon the reaction with hydrogen peroxide?
It releases the peroxidase in the liver cells.
Is the poisonous hydrogen peroxide produced in the cells of living things converted into harmless materials by the action of enzyme catalase?

Household food items that can break down hydrogen peroxide?
potatoes or liver anything with the enzyme catalase
Why liver cells give more oxygen than potato cells for catalase reaction?
the liver has more enzymes that the potato (a starch) does.
How enzyme function in the liver would be affected in a person with cirrhosis?
The enzyme function would not be as effecient, causing the liver to produce more enzymes.
