The purpose of this experiment is to discover which environmental factors, the independent variables, are most optimal for enzyme functionality and how they affect enzyme functionality. Enzymes help speed up chemical reactions in the body and lower the activation energy to do so. Enzymes can also aid with metabolism and digestion. They can break down larger molecules to smaller molecules that are more easily absorbed by the body. A substrate is the reactant that is acted upon by an enzyme in a chemical reaction. The substrate attaches itself to the active site, the place where the enzyme catalyzes.
The process for enzyme and substrate interaction is called induced fit. The process in explanation, “When an enzyme binds to its substrate, it forms an enzyme-substrate complex...The enzyme will always return to its original state at the completion of the reaction...After an enzyme is done catalyzing it releases its products”(Boundless, 2015). This lab demonstrates an enzyme’s functionalities by using the enzyme called catalase. Catalase helps break down hydrogen peroxide, the substrate, to water and oxygen, the products. To illustrate its effectiveness “Catalase prevents the accumulation of and protects cellular organelles and tissues from damage by peroxide... In mammals, catalase is found

An acidic solution is filled with hydrogen ions, while a basic solution is relatively lacking hydrogen ions. The pH has a scale from 0 to 14. 0 to 6 is acidic, while 8 to 14 is alkaline, and 7 is neutral, In this lab pH’s of 3, 7, the control, and 11 are used to represent acidic, neutral, and alkaline environmental factors. A human’s body needs both alkalinity and acidity, therefore the average pH of one’s body is around 7.4. The effect of pH on enzymes can alter the shape and functionality of it and even change the properties of the substrate, unabling it to bind to the active site. The optimum pH for catalase is around

    Introduction Enzymes, which speed up a chemical reaction without being consumed or changing the products of the reaction, are very important because they control the cellular activity of all living organisms. Enzymes are also described as being “catalysts”. In biological systems, specific enzymes catalyze particular cellular reactions. Each enzyme has a unique 3-D shape, and this shape determines which reaction it catalyzes. However, in order for a chemical reaction to move forward, an energy barrier…

    experiment, the effect of environmental conditions on enzyme functions was tested. The materials needed for the experiment was an amylase enzyme to lower the activation energy of the reactions, starch solutions of pH 3,4,5,6,7,and 8, these provided different concentrations to project various environmental conditions. In addition, Iodine solution, and a spectrophotometer were needed. Each cuvette contained a specific pH concentration. Then the enzyme extract was added to each pH concentration for a reaction…

    effect the rate of enzymes were tested: concentration, temperature, and pH levels; to try and find the absorbance rate of all three factors of enzymes. Each one being measured by a spectrophotometer every twenty seconds for 120 seconds. Eleven test tubes were numbered from one to eleven as well as eleven cuvettes. Each cuvette received one drop of guaiacol, three drops of hydrogen peroxide, and 2.8 mL of pH 7 buffer. Each test tube received different contents to measure the enzyme activity. The test…
