Investigating Enzymatic Reactions

    Cards (10)

    • What are enzymes?
      Enzymes are biological catalysts that speed up chemical reactions in living organisms.
    • What is the active site of an enzyme?
      The active site of an enzyme is the region where substrate molecules bind and undergo a chemical reaction.
    • How does temperature affect enzyme activity?
      Temperature affects enzyme activity by increasing reaction rates up to a certain point, after which activity declines.
    • What happens to an enzyme if the temperature is too high?
      If the temperature is too high, an enzyme can denature, losing its shape and functionality.
    • How does pH affect enzyme activity?
      pH affects enzyme activity by altering the enzyme's shape and charge, which can enhance or inhibit its function.
    • What is the purpose of an enzyme-substrate complex?
      The purpose of an enzyme-substrate complex is to facilitate the conversion of substrates into products during a chemical reaction.
    • How can enzyme activity be measured in a lab?
      Enzyme activity can be measured by assessing the rate of product formation or substrate consumption in a reaction.
    • Why is it important to control variables in enzyme experiments?
      Controlling variables in enzyme experiments is important to ensure that the results are valid and can be attributed to the enzyme activity alone.
    • What is the optimum pH for most human enzymes?
      The optimum pH for most human enzymes is around 7.4.
    • What does it mean when an enzyme is denatured?
      When an enzyme is denatured, it loses its three-dimensional structure and, consequently, its functionality.
