Enzymes Joshua Gomez P.1 Enzymes are classified as macromolecular biological catalysts, that help accelerate chemical reactions. It DOES NOT get used up in said reaction. The molecules upon which enzymes may act are called substrates. The enzyme subsequently converts the substrates into different molecules called products. Activation energy, being “the minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction.” There are, however, other factors that affect the reactors and the reactants in a chemical reactions. Changes in molecules like pH may not only affect the shape of an enzyme but it may also change the shape or charge properties of the substrate so that either the substrate cannot bind to the active site or it cannot catalyze. pH allows an enzyme a “peak activity, based on its pH level. Within a narrow range, it may reach said activity. Optimum pH reflects the pH of the fluid where the enzyme is locally found, like the stomach, saliva, and small intestine, just to name a few. Enzymes help our body function in numerous ways. Enzymes help us fight bacteria and other diseases. Some species of fungi, bacteria, and other parasites that invade our bodies and cause sickness are made up of proteins. Even a virus is protected by a protein based shell. Although enzymes are themselves proteins, there is one called protease which breaks down other proteins. High levels of protease in the blood can help to break down the disease causing vectors in our body.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
