Catalase converts hydrogen peroxide into water and oxygen.
Materials can act as catalysts to break down hydrogen peroxide into water and oxygen. Enzymes like catalase and peroxidase found in living organisms facilitate this reaction, speeding up the decomposition of hydrogen peroxide. This enzymatic effect helps protect cells from damage caused by hydrogen peroxide accumulation.
Create a control group by placing a measured amount of catalase solution in a test tube. Prepare test tubes with catalase solution at varying temperatures (e.g., using water baths at different temperatures). Add a known amount of hydrogen peroxide to each test tube and measure the rate of oxygen gas production as the catalase breaks down the hydrogen peroxide. Record and compare the rate of reaction at different temperatures to determine the effect of temperature on catalase activity.
Peroxide is actually not what does the healing. When you put Hydrogen Peroxide (chemical formula: H2O2) on your wound, it is separated into water and oxygen by the enzyme catalase. The catalase ONLY targets the hydrogen peroxide, and some of the bacteria is forced out with the oxygen (visually seen as the fizzing). THE TRUTH: Peroxide actually doesn't do much for you at all. To get a decent effect, get 4-6 cotton swabs, and wet them with water THEN Peroxide. the water will act as a mode of "transportation" for the bacteria to get out of the cut. This will slightly increase the effectiveness of a SINGLE cotton swab... which is still not much! (Thus the hole "4-6 cottonswabs" comment)
Hydrogen peroxide bonds to, and destroys cells. In doing so, it creates the bubbles you notice. Blood is made up of many cells, and therefore it reacts the same way. It is safe to use at over the counter concentrations for oral antiseptic use or cleaning wounds.
Question: What is the effect of the acidity of potato juice on the volume of foam produced when hydrogen peroxide is added to potato juice? In this investigation, the prediction that if the acidity of potato juice is decreased then the volume of foam was increased was proven incorrect. Catalase is damaged by acid. The lowest foam volume was 24 ml with the highest acidity, pH6, However the highest foam volume was an average of 42 ml with the second lowest acidity level,pH8 The third highest volume was 35 ml with the second highest acidity level pH7, and the second lowest foam volume was 30 ml with the lowest acidity level pH9.
Yeast produces an enzyme called catalase, which breaks down hydrogen peroxide into water and oxygen gas. When yeast is added to hydrogen peroxide, the catalase enzyme reacts with the peroxide, generating oxygen gas bubbles, which causes the frothing effect.

Catalase catalises the change of hydrogen peroxide, or oxygenated water (H2O2) into water (H2O) and diatom oxygen (O2). Water and oxygen, taken together are very good at rusting metals such as irons.
The product of the catalase reaction is oxygen gas, which causes bubbling when catalase breaks down hydrogen peroxide into water and oxygen. The rapid release of oxygen gas creates the bubbling effect that is characteristic of the catalase reaction.
The mass of liver affects the rate of reaction with hydrogen peroxide due to the availability of catalase, the enzyme responsible for breaking down hydrogen peroxide into water and oxygen. A larger mass of liver provides more catalase molecules, increasing the number of active sites for the reaction, which can enhance the reaction rate. Conversely, a smaller mass means fewer enzyme molecules, potentially slowing the reaction. Therefore, there is a direct relationship between the mass of liver and the rate at which hydrogen peroxide is decomposed.

When a potato is exposed to hydrogen peroxide, a reaction occurs due to the enzyme catalase present in the potato cells. This enzyme breaks down hydrogen peroxide into water and oxygen, leading to the formation of bubbles. This observation demonstrates the catalytic activity of enzymes and highlights the potato's ability to metabolize hydrogen peroxide, which is a toxic byproduct of cellular processes. The bubbling effect is a clear visual indication of this enzymatic reaction.
Detoxification is one of the liver's functions. Catalase catalyses the breakdown of Hydrogen Peroxide which is toxic (It's highly reactive so can cause cell damage. It comes from the small intestine via the portal vein, from things we eat or drink, e.g. alcohol) to oxygen and water, which are harmless.
Pulping liver can disrupt the cellular structure, releasing enzymes like catalase. When hydrogen peroxide is added, catalase catalyzes its decomposition into water and oxygen gas. This reaction can be observed as bubbling or effervescence.
All living organisms have the catalase in their body to neutralise the toxic hydrogen peroxide formed due to various metabolic activities to water and oxygen. So by grinding it may speed up this decomposition reaction.
The student's experiment in the Prelab Activity is designed to test the effect of changing the concentration of hydrogen peroxide on the rate of enzyme activity in the enzyme catalase. This involves manipulating the independent variable (concentration of hydrogen peroxide) to observe its impact on the dependent variable (rate of enzyme activity).
