Effect of Substrate Concentration on Catalase Aim: An experiment to find out how the concentration of hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information: Enzymes such as catalase are globular protein molecules with catalytic properties. A catalyst is a substrate which can alter the rate of reaction without itself undergoing any permanent change. As they are not changed my reactions which they catalyse, enzymes can be used over and over again. They are therefore quite effective in small amounts. All enzymes are specific as each one performs a particular reaction. Catalase is renowned as the fastest known enzyme. It is found in the liver where it speeds up the decomposition of hydrogen peroxide into water and oxygen, catalase has a turnover number (the number of substrate molecules which one molecule of enzyme turns into products per second) of 6 million. Its action can be demonstrated by dropping a sample...
