When blended liver is exposed to hydrogen peroxide, the catalase enzyme in the liver reacts with the hydrogen peroxide to form oxygen gas, which creates the visible bubbles in this photograph, and water.
What would happen if you mixed hydrogen peroxide and liver?
- Raw liver (fresh or frozen, thawed; one quarter pound)
- Knife
- Cutting board
- Blender
- Water
- Refrigerator
- Medicine dropper
- Large plate
- Hydrogen peroxide (new or recently purchased bottle works best)
- Measuring teaspoon
Does the liver break down hydrogen peroxide?
The liver contains more of the enzyme catalase, which breaks down hydrogen peroxide. The liver contains more because it detoxifies substances in the body. A larger amount of catalase lowers the activation energy, therefore speeds up the rate of reaction. The potato contains less of the enzyme catalase, therefore requires more activation energy, slowing down the rate of reaction.
What are the dangers of inhaling hydrogen peroxide?
Inhalation. Inhaling food grade hydrogen peroxide can cause: sore throat; cough; nausea; dizziness; headache; shortness of breath; If you have inhaled H 2 O 2, contact your doctor. Contact with skin
Does cold liver react with hydrogen peroxide?
Why does frozen liver react with hydrogen peroxide? When blended liver is exposed to hydrogen peroxide, the catalase enzyme in the liver reacts with the hydrogen peroxide to form oxygen gas, which creates the visible bubbles in this photograph, and water.

Why does hydrogen peroxide break your liver?
But why should liver contain an enzyme that helps degrade hydrogen peroxide? Because hydrogen peroxide actually forms as a product of metabolism and can do some nasty things. It can break apart to yield hydroxyl radicals that attack important biochemicals like proteins and DNA.
What happens to chicken liver in 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.
Why does boiled liver not react with hydrogen peroxide?
Hydrogen peroxide was added to the boiled liver tissue and no bubbles were produced: What explains this result? the hydrogen peroxide was denatured by the heat in the liver water is invisible carbon dioxide gas is only visible in cooler temperatures Catalase enzyme was denatured by boiling temperatures.
Is liver and hydrogen peroxide reversible?
A comparison of reaction rates with catalase preparations containing different proportions of Compound III indicated that the formation of Compound III is responsible for the reversible inhibition of bovine liver catalase at high H2O2 concentrations.
How does hydrogen peroxide affect enzyme activity?
Once you add more hydrogen peroxide to the solution, the reaction rate will increase as more substrate molecules can collide with the enzyme, forming more product. The result is an increasing amount of foam produced in your cup as you increase the amount of H2O2 in your reaction.
Why does crushed liver react faster?
What is this? The liver contains more of the enzyme catalase, which breaks down hydrogen peroxide. The liver contains more because it detoxifies substances in the body. A larger amount of catalase lowers the activation energy, therefore speeds up the rate of reaction.
Does boiled liver react with hydrogen peroxide?
Hydrogen peroxide was added to the boiled liver tissue and no bubbles were produced: What explains this result? the hydrogen peroxide was denatured by the heat in the liver water is invisible carbon dioxide gas is only visible in cooler temperatures Catalase enzyme was denatured by boiling temperatures.
When peroxide bubbles does it mean infection?
While not necessarily a “mistake”, a common misconception is that if hydrogen peroxide bubbles, it means your wound is infected. Hydrogen peroxide will bubble whether your wound is infected or not. A chemical reaction occurs while cleaning and creates little oxygen bubbles. Don't sweat over the bubbles.
Does hydrogen peroxide detox the body?
An oxygen detox bath involves the use of hydrogen peroxide as an antibacterial and antiviral; this is of great use especially for people who have been around a large group of people, whether you have traveled by bus, train, plane, or been in a crowded area; a hydrogen peroxide bath will clear your body of germs and ...
What removes hydrogen peroxide from the body?
Catalase: The enzyme that reduces peroxide and pain.
Why is hydrogen peroxide harmful to cells?
Hydrogen peroxide (H2O2) is unique among general toxins, because it is stable in abiotic environments at ambient temperature and neutral pH, yet rapidly kills any type of cells by producing highly-reactive hydroxyl radicals.
What does the liver do?
All the blood leaving the stomach and intestines passes through the liver. The liver processes this blood and breaks down, balances, and creates the nutrients and also metabolizes drugs into forms that are easier to use for the rest of the body or that are nontoxic.
What happens when you put hydrogen peroxide on your liver?
What happens when you put hydrogen peroxide on liver? When blended liver is exposed to hydrogen peroxide, the catalase enzyme in the liver reacts with the hydrogen peroxide to form oxygen gas, which creates the visible bubbles in this photograph, and water. Click to see full answer.
What happens when you add more hydrogen peroxide to a solution?
Once you add more hydrogen peroxide to the solution, the reaction rate will increase as more substrate molecules can collide with the enzyme, forming more product. The result is an increasing amount of foam produced in your cup as you increase the amount of H2O2 in your reaction.
How does hydrogen peroxide form?
In this case oxygen is generated when hydrogen peroxide breaks down into oxygen and water on contact with catalase, an enzyme found in liver. Actually, the formation of hydrogen peroxide in cells is an attempt by the body to protect itself from an even more dangerous substance, superoxide.
What happens when you mix liver with hydrogen peroxide?
Figure 1. When blended liver is exposed to hydrogen peroxide, the catalase enzyme in the liver reacts with the hydrogen peroxide to form oxygen gas, which creates the visible bubbles in this photograph, and water. In this science fair project, you will use fresh (or frozen) liver as a source of catalase and investigate how the activity ...
Why is it important to break down hydrogen peroxide?
One of the reasons breaking down hydrogen peroxide is important is because if left alone, hydrogen peroxide in the blood can produce free radicals.
How to test liver for high salt?
To test the effect of high salt conditions, put one teaspoon of the blended liver in a bowl and add one teaspoon of table salt. Mix well.
What is the name of the chemical reaction that changes the amount of hydrogen peroxide?
This is called "enzyme kinetics.". Conduct your own experiment on enzyme kinetics by changing the amount of blended liver and hydrogen peroxide in your reactions.
How to test liver enzymes?
You will be testing the enzyme activity of the blended liver in the following steps. On the cutting board, carefully cut about ¼ lb of liver into little pieces, about 1-2 centimeters in size. You may need an adult to help with this.
How to make liver smooth?
Place the cubes of liver into a blender and add an equal volume of water. Carefully blend on high speed, pulsing when necessary, until the liver is smooth and no chunks are present. Keep the blended liver in the refrigerator. Test the activity of the blended liver. Put one drop of it on the large plate.
How do enzymes speed up a chemical reaction?
Enzymes are made out of protein and they speed up the rate of a chemical reaction by acting as a catalyst. A catalyst provides the necessary environment for the chemical reaction to occur, which speeds up the reaction. Certain catalysts work for certain kinds of reactions.
