Background: In this lab, we will be observing a chemical reaction dealing with enzymes. You may ask, what are enzymes? Enzymes are proteins produced by living cells. For example, you have enzymes in your digestive system to help you break down food. Without enzymes, organisms will not be able to survive. Enzymes act as catalyst in biochemical reactions and catalyst speeds up the reaction by lowering the amount of activation energy. Activation energy is required for reactants to react into products. Although enzymes are essential, substrate plays an crucial role as well. The substrate and enzyme bind together on the active site of the enzyme, like a key to a lock. Each substrate has its own specific shape and structure. The active site of the enzyme has to be perfect in order for the enzyme-catalyzed reaction to function. There are few external impact on the shape of the active site, such as salt concentration, pH, temperature, and activations and inhibitors. First, the salt concentration cannot be too high or too low. If the salt concentration is too extreme, the amino acids will begin to attract to each other and cause denaturation. It functions similarly on the other hand. If salt concentration is too low, the amino acid interaction will be blocked and enzyme will denature. As a result, it is important to maintain the salt concentration at an intermediate level. Secondly, pH is the measure of acidity. If pH is too high, it means that the solution is too acidic. High
