The Effect Of Substrate Concentration On The Activity Of The Enzyme Catalase
Aims
This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase.
Background Information
Enzymes are protein molecules. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction.
Catalase is an enzyme found in food such as potato and liver. It is used for removing Hydrogen Peroxide from the cells which is the poisonous by-product of metabolism. Catalase speeds up the decomposition of Hydrogen Peroxide into water and oxygen as shown in the equations below.
Formula:
Catalase
Hydrogen Peroxide ----------> Water + Oxygen
Catalase
2H2O2------------------->2H2O+O2
It is able to speed up the decomposition of Hydrogen Peroxide because the shape of......
