Introduction: What is responsible for carrying out most of the processes of life throughout the body? Proteins are the macromolecules of the body that fulfill most of these important processes essential to life. Proteins are then categorized into different classes. One of those classes is enzymes which are then specified by names. The main function of enzymes is to catalyze (speed up) biological reactions by lowering the activation energy which is the amount of energy that is needed to initiate a chemical reaction. Enzymes work to lower the activation energy of only spontaneous exothermic reactions. Therefore, the function of an enzyme cannot make a reaction become spontaneous (Vodopich and Moore 2). The way enzymes work is very specific and interesting. The reason enzymes are so specific in the way they work is because there are millions of enzymes in the body that each need to be able to carry out their processes. Each enzyme has their own active site where they will recognize and bind to their specific substrate or imitators of the substrate. When the substrates are mimicked, the substrate can then block the enzymatic activity. An enzyme is then at its transitional state and goes through formational changes when a substrate binds to the enzymes active site. When this happens, the substrate is then introducing to a different environment of the enzyme which causes the substrate to be transformed into a product. This product that is created is then released from the enzyme…
