IntroductionEnzymes are macromolecules that act as a catalyst, and it is a chemical agent that speeds up the reaction without being consumed by the feedback or results (Campbell and Reece, 2005). After adjustment by enzymes, chemical movement through metabolism pathways will become terribly congested because many chemical reactions take a long time (Campbell and Reece, 2005). There are two types of reactions in nature. The first is the catabolic reaction and the second is the anabolic reaction. Catabolic reactions are large molecules being broken into smaller molecules (Ahmed, 2013). Anabolic reactions are small molecules joining together to form larger molecules, such as polymerization (Ahmed, 2013). If you put all the reactions together, catabolic and anabolic reactions are called metabolism (Ahmed, 2013). Basically, enzymes are protein molecules that can be composed of one or more multiple polypeptides (Ahmed, 2013). Enzymes can also contain non-protein parts called cofactors to which they are attached (Ahmed, 2013). “If the cofactors are organic in nature, they are called coenzymes” (Ahmed, 2013). Whether an enzyme catalyst expands its reaction rate varies depending on factors such as temperature, pH, substrate concentration, enzyme concentration, etc. (Ahmed, 2013). The enzyme has five properties: the first is that the enzyme binds to the substrate, the second is that enzymes are substrate specific, the third is that the substrate binds to an enzyme at the active site (Ahmed, 2013). The last two properties are “Enzymes are not consumed in a reaction” and “Enzymes work best at optimal temperature and pH” (Ahmed, 2013). Any particular study will cause changes in reaction speed due to the difference between the medium of the paper and the factors, causing them to react significantly as we expect them to react.
