Transcript

  • 1. Chemical Compounds in Cells
  • 2. Elements
    • An element is any substance that cannot be broken down into simpler substances.
    • The smallest unit of an element is an atom.
    • Example of an element is carbon.
  • 3. Compounds
    • A compound is two or more elements that are chemically combined.
    • The smallest unit of a compound is a molecule.
    • An example of a compound is water.
  • 4. Organic and Inorganic Compounds
    • Inorganic compounds do not contain carbon.
    • Organic compounds contain carbon and hydrogen and usually are associated with living things.
  • 5. Four groups of Organic Compounds
    • Carbohydrates
    • Lipids
    • Proteins
    • Nucleic Acids
  • 6. Carbohydrates
    • Made of the elements carbon, hydrogen, and oxygen
    • Supply energy for cell processes, form plant structures; short-term energy storage
    • Sugars-fruits, starch-pasta, and cellulose-found in cell walls of plants
  • 7. Lipids
    • Made of the elements carbon, hydrogen, and oxygen
    • Store large amounts of energy long term; form boundaries around cells
    • Fats, oils, waxes, phospholipids, and cholesterol
  • 8. Proteins
    • Made of the elements carbon, oxygen, hydrogen, nitrogen,and sulfur
    • Regulate cell processes and build cell structures
    • Enzymes, skin, and hair
  • 9. Nucleic Acids
    • Made of the elements carbon, oxygen, hydrogen, nitrogen, and phosphorus
    • Carry hereditary information; used to make proteins
    • DNA and RNA
