Aim: In this experiment I am going to investigate the difference of oxygen that is given off between mushy potato and liver. When contained in a quantity of hydrogen peroxide. Background Information: Catalyse is an enzyme found in food such as potato and liver. It is used for removing Hydrogen Peroxide from the cells. Catalyse speeds up the decomposition of Hydrogen Peroxide into water and oxygen. It is able to speed up the decomposition of Hydrogen Peroxide because of the shape of the Hydrogen Peroxide molecule. This type of reaction where a molecule is broken down into smaller pieces is called an anabolic reaction. Catalyse 2H202 ---> 2H2O + O2 Hydrogen peroxide --> water + oxygen (+heat) Enzymes are proteins that act as catalysts. They are made in cells. A catalyst is something that speeds up a reaction, but does not get used up in the reaction. One can usually be used many times....
