Presentation Transcript

  1. Warm-up 1/31/12 • Teach the Teacher: What is the best kind of candy to get at the gas station? • Review: What are the three parts of an experiment. • Learning Target: Defend Whether something is alive or not. • Identify the 4 types of macromolecules.

  2. Flash Card • On the Front Write: • Characteristics of Life • On the Back write: • Made of cell (s) • Organization • Grows • Reproduces • Responds to stimuli • Requires energy • Homeostasis • Has adaptations

  3. Building Blocks of Cells

  4. Macromolecules • Macro=large • Molecules=two or more atoms bonded together, like H20 • Tons of repeating molecules bonded together to make…macromolecules • Think of them like the wood for building the framing of a house

  5. 4 types of Macromolecules • Carbohydrates • Lipids • Proteins • Nucleic acids Just like there are different materials used to make a house…different materials to make a cell.

  6. In foods=sugar and starches Carbohydrates • Store energy • Sucrose, lactose, glucose • Provide structural support • Cellulose makes cell wall of plants • Chitin is hard outer layer in the hard outer shell of shrimp, lobsters, and some insects

  7. Lipids • Made up of carbon and hydrogen • Make up fats, oils, waxes • Coated on leaves (wax) • Beeswax for honeycomb • Store Energy • Provide Barriers for cells • Phospholipids • Include steroids and cholesterol

  8. Lipids • Good lipids (fats) • UnSaturatedfats • Not so good lipids (fats) saturated fats • Saturated refers to the number of hydrogens that can fit on the macromolecule

  9. Proteins • Made of small carbon compounds • Made of amino acids • Think DNA • Used in every function of your body! • 10,000 different proteins

  10. Proteins • Transport substances • Speed Reactions • Provide structural support • Make hormones

  11. Nucleic Acids • Store and communicate genetic information • made of carbon, nitrogren, oxygen, phosphorus, and hydrogen atoms

  12. Notes To Notes Card • Write your name and period on the note card, and use your notes to answer the following questions: • What are the four main macromolecules? • Which macromolecules provide structural support? • What is a macromolecule? • Which fat is the good kind of fat? • What type of macromolecule is used for barriers, like in honeycomb?
