Why does chicken liver react with hydrogen peroxide?

The cells that make up the chicken liver contain enzymes that speed up the breakdown hydrogen peroxide. These enzymes are acting as catalysts because they are speeding up the rate of a chemical reaction, in this case the breakdown of hydrogen peroxide. This is an example of an “exergonic” reaction.

What enzyme from the liver breaks down peroxide?

How does that happen? A foam forms when bubbles of a gas are trapped in a liquid or solid. In this case oxygen is generated when hydrogen peroxide breaks down into oxygen and water on contact with catalase, an enzyme found in liver.

What is the chemical equation for liver and hydrogen peroxide?

The reaction is: 2H2O2 → 2H2O + O This reaction is important to cells because hydrogen peroxide is produced as a byproduct of many normal cellular reactions.

Does the liver break down more hydrogen peroxide in summer or winter?

There is a large amount of catalase found in a human liver. Does the liver break down more hydrogen peroxide in the summer or winter? Explain your answer. More hydrogen peroxide will be broken down in the summer…show more content…

How to test the effect of hydrogen peroxide on the liver?

2. Put 1.4g of liver in a test tube with delivery tube. Add sand to all experiments to have a fair test with the liver that is ground up (sand separates the liver easily). 3. Add 10cm’ of hydrogen peroxide to the liver. Replace the bung quickly so that no gas is lost. 4. After 10 seconds record the amount of water displaced in the burette.

Which is enzyme breaks down hydrogen peroxide in the liver?

Catalase is an enzyme in the liver that breaks down harmful hydrogen peroxide into oxygen and water. When this reaction occurs, oxygen gas bubbles escape and create foam. Materials. • Raw liver (fresh or frozen, thawed; one quarter pound)

Can you add hydrogen peroxide to a blended liver?

Be careful of the sharp blades in the blender. • Keep the blended liver in the refrigerator. • Put one drop of the blended liver on the large plate. To the blended liver drop, add one drop of hydrogen peroxide. You should see a lot of bubbles! What do you think the bubbles are made of?

Why does the liver break down more hydrogen peroxide than the potato?

Explain why there is a difference in the rates of reaction between the liver and the potato The liver contains more of the enzyme catalase, which breaks down hydrogen peroxide. The liver contains more because it detoxifies substances in the body.
