A Investigation into the Effect of Inhibitor Concentration on the Enzyme Catalase Aim: To investigate how the concentration of inhibitor (lead nitrate) affects the rate of reaction of the enzyme Catalase. Hypothesis: In my hypothesis I state that Hydrogen Peroxide (H O ) will breakdown to oxygen and water in the presence of catalase from the potato. The rate of reaction will decrease with increasing inhibitor (lead nitrate) concentration when molecules of Hydrogen Peroxide are freely available. However, when molecules of the inhibitor are in short supply, the increase in the rate of reaction is limited and therefore will have little affect. Predicted Graph: Background Knowledge: Enzymes- Enzymes are complex 3-D globular proteins, some of which have other associated molecules. Enzymes are catalysts which alters the rate of chemical reaction without itself undergoing a permanent change, and therefore can be used over and over again. Enzymes help reactions speed up which would otherwise take place...
