peroxide anion
Hydrogen peroxide (H2O2) reacts naturally in air to form oxygen and water. 2H2O2 > 2H2O + O2 Catalase is an enzyme found in most organisms which catalyses this process, so the bubbles you see are oxygen.
The building block for catalase is a protein molecule made up of amino acids. Each amino acid is connected to form a chain that folds into a specific structure, which is critical for the catalytic activity of the enzyme.
The substrate of catalase is hydrogen peroxide, which is broken down into water and oxygen. Catalase is a tetrameric protein made up of four subunits that come together to form a globular shape with a heme group at the center.
Coagulase is an enzyme that is found in Staphylococcus aureus but not in Staphylococcus epidermidis. It helps S. aureus to form blood clots and evade the host immune response.
The bubbles could be viewed as a sign that the peroxide is "eating" the bacteria. You will notice after a while that fewer and fewer bubbles appear, that is because the bacteria is getting killed.

When hydrogen peroxide reacts with catalase, an enzyme found in cells, it breaks down the hydrogen peroxide into water and oxygen gas. The oxygen gas is produced in the form of bubbles due to the rapid release of oxygen gas during the decomposition reaction. This reaction is catalyzed by catalase, which helps speed up the decomposition of hydrogen peroxide into water and oxygen.
The building blocks of the enzyme catalase are amino acids. These amino acids are arranged in a specific sequence to form the catalase protein, which catalyzes the breakdown of hydrogen peroxide into water and oxygen.
The reason why it foams or bubble is because blood and cells contain an enzyme called catalase. Since a cut or scrape contains both blood and damaged cells, there is lots of catalase floating around. When the catalase comes in contact with hydrogen peroxide, it turns the hydrogen peroxide (H2O2) into water (H2O) and oxygen gas (O2).

The substrate of catalase is hydrogen peroxide, which is broken down into water and oxygen. Catalase is a tetrameric protein made up of four subunits that come together to form a globular shape with a heme group at the center.
The reaction of catalase with hydrogen peroxide is exothermic, meaning it releases energy in the form of heat as the reaction proceeds. Catalase helps break down hydrogen peroxide into water and oxygen in living organisms.
The equation for the reaction is 2 H2O2 → 2 H2O + O2 Each molecule of hydrogen peroxide is split into a molecule of water and an oxygen atom. The oxygen atoms pair to form oxygen molecules. Catalase is one of the most vigorous enzymes known, and the rush of oxygen to the surface of the liquid is spectacular.

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.
The reaction between liver and hydrogen peroxide is exothermic because it releases energy in the form of heat as new chemical bonds are formed during the breakdown of hydrogen peroxide by catalase enzyme in the liver. The enzyme catalyzes the decomposition of hydrogen peroxide into water and oxygen, resulting in the production of heat energy.
