Catalyst.
MnO2 is the chemical formula(there is no equation). The compound is called manganese oxide and manganese(IV) oxide by IUPAC. Wikipedia calls it manganese dioxide.
Yeast does not react with hydrogen peroxide but it is a catalyst. Hydrogen peroxide (H202) decomposes into H2O and O2. This is always happening but at a very low rate so you don't notice it. If you add yeast to hydrogen peroxide it will speed up the decomposition of H2O2. However the yeast does not react with the H2O2 and nothing is chemically altered in the yeast. That is because yeast is a catalyst.

A chemical called glucose oxidase is commonly used to detect glucose. This enzyme reacts with glucose in the presence of oxygen, producing hydrogen peroxide as a byproduct. The level of hydrogen peroxide produced is then typically measured as an indicator of the glucose concentration in a sample.
In aerobic respiration glucose is broken down to release energy and the only toxic products formed are carbon dioxide CO2 and apart from that excess water and it is not difficult to get rid of these things.This is called excretion (removal of toxic waste products of metabolism.)
The catalyst for the decomposition of hydrogen peroxide is typically an enzyme called catalase, which is found naturally in living organisms including plants and animals. Catalase speeds up the breakdown of hydrogen peroxide into water and oxygen gas.
Peroxisomes are organelles that has an enzyme called catalase. This enzyme breaks down a harmful substance like hydrogen peroxide in cells to convert it into oxygen and water, which are harmless products.
When liver and hydrogen peroxide mix, they produce a liquid called hydrogen peroxide. The liver contains an enzyme called catalase, which breaks down hydrogen peroxide into water and oxygen gas.
The material most commonly called "hydrogen peroxide", especially by non-chemists, is a solution of the solute hydrogen peroxide in water as the solvent.
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). H2O2 --> H2O + O2 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.

The enzyme in potatoes that breaks down hydrogen peroxide is called catalase. Catalase helps to convert hydrogen peroxide into water and oxygen, which prevents oxidative damage in the potato cells.
When hydrogen peroxide reacts with yeast, an enzyme called catalase in the yeast breaks down the hydrogen peroxide into water and oxygen gas. This reaction is exothermic and produces bubbles of oxygen gas as a byproduct.
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.
Catalases are enzymes that catalyse the conversion of hydrogen peroxide to water.
Peroxisomes contain enzymes called catalase that degrade hydrogen peroxide into water and oxygen gas. This process helps protect the cell from the toxic effects of hydrogen peroxide.
MnO2 is the chemical formula(there is no equation). The compound is called manganese oxide and manganese(IV) oxide by IUPAC. Wikipedia calls it manganese dioxide.
The enzyme catalase converts hydrogen peroxide into water and oxygen. Catalase breaks down hydrogen peroxide into water and oxygen by catalyzing the decomposition reaction. This enzyme is found in cells, particularly those with high metabolic activity to help remove harmful byproducts like hydrogen peroxide.
