    Section 4 - Biochemistry Section 4 - Biochemistry Presentation Transcript

    • Biochemistry Biology I Factoids
    • Factoid #24
      • Organic chemistry is the study of carbon compounds produced by living things.
    • Factoid #25
      • All organic molecules contain carbon, hydrogen and oxygen.
    • Factoid #26
      • Polymers are organic macromolecules made up of monomers.
    • Factoid #27
      • The 4 macromolecules in organic chemistry are carbohydrates, lipids, proteins, and nucleic acids.
    • Factoid #28
      • Carbohydrates are made of monosaccharides.
    • Factoid #29
      • Carbohydrates include sugars (ends in –ose), starch (in plants), glycogen (in animals), and chitin (in fungus and insects).
    • Factoid #30
      • Lipids are made up of glycerol and fatty acids.
    • Factoid #31
      • Lipids include all oils, waxes, steroids, and fats.
    • Factoid #32
      • Proteins are made up of amino acids.
    • Factoid #33
      • Nucleic acids are made up of nucleotides.
    • Factoid #34
      • Nucleic acids include DNA and RNA.
    • Factoid #35
      • Enzymes are proteins that lower the activation energy and speed up chemical reactions.
    • Factoid #36
      • The substance the enzyme works on is called the substrate.
    • Factoid #37
      • Most enzymes end with –ase such as polymerase or catalase.
    • Factoid #38
      • When catalase breaks down hydrogen peroxide, hydrogen peroxide is the substrate of the reaction.
    • Factoid #39
      • The spot on the enzyme where the substrate binds is called the active site.
    • Factoid #40
      • Both pH and temperature will change the shape of the active site and the enzyme won’t work – this is called “denaturing” the enzyme.
