Record the effect that the enzyme catalase found inside the potato has, when added to hydrogen peroxide, and whether to not there is a change in the rate of reaction when the surface area of the potato is increased.

PLANNING Enzymes Background Information Enzymes such as catalyse are protein molecules, which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. 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. Aim: Carry out an experiment on enzyme activity. The aim is to record the effect that the enzyme catalase found inside the potato has, when added to hydrogen peroxide, and whether to not there is a change in the rate of...
