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).

Why does boiled liver react with Hydrogen Peroxide?

Boiled liver reacts with hydrogen peroxide because liver contains enzymes called catalase, which catalyze the breakdown of hydrogen peroxide into oxygen gas and water. This reaction produces bubbles of oxygen gas, which is visible as a foamy reaction when hydrogen peroxide is added to boiled liver.

Why doesn't macerated liver react with hydrogen Peroxide like liver does?

Macerated liver has been treated and processed in a way that destroys the enzymes responsible for catalyzing reactions with hydrogen peroxide. Without these enzymes, such as catalase, macerated liver does not exhibit the same reaction with hydrogen peroxide as fresh liver.


What is a metal that reacts to salt water but does not react to fresh water?

Magnesium. I believe Magnesium does not react to fresh water but salt water is very corrosive and will disolve the metal.


Does the potato react more like the liver or the tap water?

Tap water


Does cold liver react with hydrogen peroxide?

Yes, cold liver will react with hydrogen peroxide because liver contains enzymes that can catalyze the breakdown of hydrogen peroxide into water and oxygen gas. This reaction is commonly used in biology experiments to demonstrate enzyme activity.


What will happen to a fresh piece of lithium react with oxygen in the air?

A fresh piece of lithium will react with oxygen in the air to form lithium oxide. This reaction is exothermic and can produce heat, light, and potentially even a fire.


Why does macerated liver react faster than whole liver on hydrogen peroxide?

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.


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.

Why is there no reaction when liver is placed in hydrochloric acid and peroxide?

The liver does not react with hydrochloric acid and peroxide because the liver is mainly composed of proteins and fats, which are not easily broken down by these substances. The enzymes and properties that usually cause chemical reactions in the liver are denatured or deactivated by the acid and peroxide, resulting in no significant reaction.
