Enzymes are organic catalysts that speed up metabolic reactions (Denniston, 2007). In short, enzyme functions by binding one or more of the reactants in a reaction. Specific enzymes only lower the activation energy for specific reactions and enzymes are shape-specific. The reactants that bind to the enzyme are known as substrates of the enzyme. The exact location on the enzyme where substrate binding takes place is called the active site of the enzyme. When substrates fit perfectly into the enzyme’s active site, the enzyme is able to catalyze the reaction (Denniston, 2007). The activity of enzymes is affected by both the concentrations of enzymes present and the substrate concentrations present. As the number of enzyme upsurges, the enzyme’s reaction rate also rises. Also, as the number of substrate upsurges, the enzyme’s reaction rate initially increases. Enzymes have to be met at an equilibrium in order to work properly and efficiently. These conditions include temperature, the concentration of salt, and the pH level. If the equilibrium for an enzyme was altered, the enzyme may denature, or change its shape, and deactivate. (Richard B. Silverman, 2002). As a result, the enzyme would no longer be able to catalyze the reaction and the reaction rate would significantly decrease
