Presentation Transcript

  1. Catalyst • Rank the following foods, with the food you think is healthiest at the top and the unhealthiest at the bottom. • Whole wheat bread • Crunchy Peanut Butter • Orange Juice • Cheetos • Bagel • Turkey breast • Soy beans • Chocolate chip cookie

  2. Macromolecules • Monomers: Molecules that link to make macromolecules/polymers. • 4 Main Macromolecules “one” “many” monomer – monomer – monomer polymer/macromolecule

  3. Macromolecules • Carbohydrate / Polysaccharide (Macromolecule) • Monosaccharide (Monomer) • Function: Store short term energy • Food Sources: Grains (carbohydrate), Candy (Monosaccharide) • Connections: “Carb-Loading” before a race. • Monosaccharide (“Simple Carbs”) • Glucose Molecule “Sugar” Carbohydrate / Polysaccharide (“Complex Carbs”)

  4. SIMPLE VS. COMPLEX CARBS • Simple carbs are easily and quickly digested • Also known as simple sugar • Get their name because they are made up of only one or two sugars • Examples: table sugar, soda, candy • Complex carbs take longer to digest • Also known as starch • Get their name because they are made up three or more sugars • Examples: bread, pasta, grain

  5. Carb-Loading • http://www.youtube.com/watch?v=rNL8LbQ80dI

  6. Macromolecules • Lipid (Macromolecule) • Glycerol Molecule + Fatty Acid Tails (Building Blocks) • Function: Store long term energy, cushioning • Food Sources: Oils, Fats, Waxes • Connections: Fat cells synthesize & breakdown lipids Zoom-In Glycerol Molecule Polar / Hydrophilic(Loves Water) Fatty Acid Tails (Any #) Nonpolar / Hydrophobic (Hates Water) Lipid

  7. Your fat looks like this…

  8. Macromolecules • Protein / Polypeptide (Macromolecule) • Amino Acids (Monomer) • Function: Enzymes, Hormones, Structural Support, Cell Communication • Food Sources: Meat, Eggs, Beans, Soy, Milk • Connections: Protein powder to “build muscle”. Zoom-In H Protein Cys Leu Side chain changesfor each of the 20amino acids. Ser H2N C COOH Phe Leu R

  9. Make your own protein shake! • http://www.youtube.com/watch?v=zZuGs7LML-Q

  10. Macromolecules • Nucleic Acid (Macromolecule) • Nucleotides (Monomer) P Zoom-In P Nucleic Acid Key P = Phosphate Group P = Sugar (“-ose” Nucleotide = Nitrogenous Base Image Source: www.astrochem.org

  11. Macromolecules • Nucleic Acid (Macromolecule) • Nucleotides (Monomer) • Function: Store and transmit genetic information; “blueprints” • Examples: • DNA (deoxyribonucleic acid) • RNA (ribonucleic acid) • ATP (adenosine triphosphate) NucleicAcids deoxyribose sugar ATP P P P ribose sugar Nucleotide Break this bond for ENERGY!

  13. Macromolecule Stations • 4 stations • Simple carbs • Complex carbs • Protein • sugar • Fill out the table for the station you’re assigned, and then rotate (after approval from Ms. Adabale) • You have about 7 minutes at each station

  14. Cells • Levels of Organization • Cells: • All life has ≥1 cell(s) • Basic unit of life (anything before is not living) • Cells come from other living cells Protons Electrons Neutrons Atoms Molecules Monomers Macromolecules/ Polymers Cells Organisms

  15. Scavenger Hunt • You are working with your table • You have 15minutes to get as much done as you can. • As soon as you’re done, or after 15 minutes (whichever comes first), come back to class.

  16. Homework • Create a book of Macromolecules • Fold 3 sheets of letter-sized paper horizontally • First page should include your name, period, and date • Dedicate 2 pages/macromolecule • Pages must include: polymer and monomer name, picture of polymer and monomer, function, and at least 2 examples • Make it colorful! • Decorate the cover of your book
