  1. Reporting Category 1 Cell Structure and Function Station 6 Biomolecules

  2. Essential Question- Bell Ringer • Biomolecules are organic molecules produced by living organisms. Which biomolecule is produced during the process of photosynthesis and used as an energy source in cellular respiration? The biomolecule produced during photosynthesis is glucose, C6H12O6, and it is used as the energy source in cellular respiration

  3. Pre-Review Question Which elements do all biomolecules have in common? Carbon, Hydrogen and Oxygen

  4. Pre-Review Question Which of the following biomolecules is used as a primary source of energy? • Lipids • Carbohydrates • Nucleic Acids • Proteins

  5. Pre-Review Question Which of the following biomolecules is used as a secondary source of energy? • Lipids • Carbohydrates • Nucleic Acids • Proteins

  6. Discuss with your partner Biomolecules are molecules that are synthesized by living cells. Why are biomolecules important? These molecules control almost every aspect of life processes.

  7. Discuss with your partner Most biomolecules are macromolecules. How do a biomolecule’s size and the number of bonds it contains affect the amount of energy that is available? As the molecule size increases, so does the number chemical bonds needed to hold the structure together. These bonds contain energy, which enables the molecule to perform its functions. The more energy contained within the molecule, the more work the structure can do once the energy is released. Energy is released when the bonds holding the atoms together are broken.

  8. Discuss with your partner The station has three different models of each biomolecule: a 3-D model, a structural formula, and a chemical formula (mathematical model). Locate the 3-D model of glucose. Count and record, in the table below, the number of carbon, hydrogen, and oxygen atoms represented in the model. Type of atom Number present carbon oxygen hydrogen 6 6 6

  9. Copy the chart in your journal and fill it in. See how much you can remember before you check your notes.

  10. Copy the chart in your journal and fill it in. See how much you can remember before you check your notes.

  11. Station 6. I need to remember.. Sugars, the smallest carbohydrates, serve as fuel. Lipids store large amounts of energy. A protein’s function depends on its unique sequence of amino acids. Nucleic acids store and transmit hereditary information. Organic molecules contain carbon–hydrogen bonds and are produced by organisms.

  12. Post Review Questions • Fatty acids and glycerol are the monomers of _____? Lipids 2. Simple sugars can be found under ____? Carbohydrates 3. Genetic information is in ___________? Nucleic Acid 4. Almost all enzymes are ______? Proteins
