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. ScienceBiologyLifeCells

5. Macromolecules Macro=large Molecules=two or more atoms bonded together, like H 2 0 Tons of repeating molecules bonded together to make…macromolecules Think of them like the wood for building the framing of a house

6. 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.

7. 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 In foods=sugar and starches

8. 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

9. Lipids Good lipids (fats) ▫UnSaturated fats Not so good lipids (fats) saturated fats Saturated refers to the number of hydrogens that can fit on the macromolecule

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

11. Proteins Transport substances Speed Reactions Provide structural support Make hormones

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

13. Notes To Notes Card Write your name and period on the note card, and use your notes to answer the following questions: 1.What are the four main macromolecules? 2.Which macromolecules provide structural support? 3.What is a macromolecule? 4.Which fat is the good kind of fat? 5.What type of macromolecule is used for barriers, like in honeycomb?
