    An enzyme is a tertiary globular protein. The function of an enzyme is to lower the activation energy of either the creation or breaking apart of a chemical bond. By lowering the activation energy of this process, the reaction of bonding, or in this case breaking apart, is sped up. An enzyme breaks apart the substrate in the active site of the enzyme; this is where the magic happens. Substrate is what is being broken apart by the enzyme. In this case, the enzyme is catalase and the substrate is hydrogen...

  • Effect of Temperature on Enzyme Activity

    the Effect of Temperature on Enzyme Activity Almost all chemical reactions that occur in living organisms are catalyzed by enzymes. Many factors in a cell’s environment affect the action of an enzyme. In this investigation, you will design an experiment to determine the effect of temperature on an enzyme-catalyzed reaction. You will complete an entire lab write-up using the CHS LAB REPORT FORMAT. Fundamental Question How does temperature affect the rate of an enzyme-catalyzed reaction? Materials ...

    Enzyme Lab Introduction/ Abstract An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. They are mainly made up of proteins and can tremendously speed up reactions. E. coli ( a bacterium) has about 1,000 different types of enzymes floating around in its cytoplasm at any given time. Enzymes can be used to join and even break up molecules as shown in the diagram below. (1)...

    (Danyk, H, 2013). Quinones are produced by the oxidation of phenolic compound of catechol. Enzymes are used to speed up chemical reactions in cells (Danyk, H, 2013). The enzyme catechol oxidase is used to speed up the production of benzoquinone which is to help in infection prevention. In this study catechol oxidase was combined with potato juice extract and water. To provide more results of the enzymes productivity patterns the solutions; temperatures were changed, alterations were made in...
