These enzymes are specific because they are each folded into a specific shape, within the folds of the shapes is an active site, or the site where the reaction takes place. The DNA in cells codes all the information necessary to make many different enzymes and they are produced using this code whenever the cell feels the need for a particular enzyme.Įnzymes are very specific, meaning that there are certain ones made to act on and recognize certain substrates, or the molecules on which an enzyme acts. Each enzyme has a specific functions that carry out the reactions necessary for life. These enzymes are made by cells and can be used over and over. Introduction: Enzymes are molecules that act as catalysts to chemical reactions in the body. The result of the experiment will show the relationships between the concentration of enzymes and the time of the reaction and the concentration of the substrate and the time of the reaction. The amount of concentrations of enzymes and substrates are changed to determine if the reaction is further catalyzed by a greater concentration of enzymes or substrates. The higher the concentration of potato extract, or catalase, the faster the reaction and the more substrate present will result in a decrease in the time of the reaction.
In this experiment the substrate hydrogen peroxide and the enzyme catalase will be used. Abstract: Enzymes, molecules that speed up chemical reactions, are specific to one substrate.
