  1. Macromolecules Lesson #11

  2. Lesson #11 Macromolecules Objective: Identify macromolecules, and their roles Catalyst Collect your graded work from the folder in the back. Write down today’s topic in your T.O.C. • Take out the quiz from last week. Write down the correct answers, and a 1-2 explanation of why they are the correct answers. (You’ll want to talk to the person next to you if you don’t know the answer yourself)

  3. Making a goal for this week

  4. A lot of you reached our goal on that quiz! • 85% • Why 85%? • Sign the back wall

  5. Congratulations to… • Jarrod (100%) • Jynico (100%) • Jasmine • Trakeya • Shuvaughn • Melissa • Wendell • Tyree

  6. Hmmm:Can you get pregnant without having sex? • Normally no. But… • In Vitro fertilization • Over 3 million! • Louise Brown, first baby

  7. Housekeeping • TEST on Thursday • Prokaryotic, eukaryotic • Organelles • Characteristics of life • Macromolecules • Tardiness check • Binder check today

  8. Binder Check • Write down the number of points they got • Sum the points on the bottom

  9. Agenda Food discussion Explore activity Lecture Worksheet What are we doing today?

  10. Today’s question: What makes something a food? • For example, why do we eat things like apples and chicken, and not things like aluminum foil or rocks? • Why do eat?

  11. One answer… • Food is made of the same things, that we are • Therefore, to figure out what we’re made of, we can look at what food’s made of

  12. Some background…

  13. Smallest units of matter Alive? Not alive Atoms

  14. Bunches of atoms stuck together Alive? No TODAY’S FOCUS IS ON MOLECULES! Molecules

  15. Unicellular organism: made of only 1 cell Alive? YES! Most basic unit of life Cell7,000,000,000,000,000 atoms

  16. Our activity • Food is made of the same things, that we are • Therefore, to figure out what we’re made of, we can look at what food’s made of SO… • Let’s see what MOLECULES food is made of ACTIVITY • Go around to the stations • Write down: hypothesis of what molecules living things are made of

  17. Debrief

  18. NOTES

  19. Notes

  20. The Molecules of Life • All living things have four types of macromolecules. • Macro-: big • Proteins • Carbohydrates • Lipids • Nucleic Acids

  21. Polymers • All macromolecules are polymers. • Key Point #1 • A polymer is a connected string of monomers.

  22. Check Yourself… • What is a macromolecule? • What are the four macromolecules? • What is a polymer? • Proteins are polymers of what? • What are some of the important functions of proteins? • What determines how proteins work?

  23. Carbohydrates • Carbohydrates (AKA sugars) are polymers of monosaccharides, making a polysaccharide. • Monosaccharides have a general formula of CH2O • There are 3-carbon sugars (triose), 5-carbon sugars (pentose), and 6-carbon sugars (hexose).

  24. Monosaccharides • The most important monosacchardies that you need to know is gluose: C6H12O6.

  25. Disaccharides • When you put two monosaccharides together, you get a disaccharide.

  26. Polysaccharides • As you keep adding more and more monosaccharides, you’ll end up with a polysaccharide.

  27. Functions of Carbohydrates • Key Point #2 • Carbohydrates are for short-term energy storage for most living things • Provide structural support in plants. • Plant store energy as starch (think potatoes) • Animals store energy as glycogen in muscle & the liver. • All plant cell walls are made of cellulose.

  28. Lipids • Key Point #3 • Lipids are NOT polymers and are all nonpolar and hydrophobic. • Hydro-: water • -phob-: fearing • Since water is a polar molecule, they repeal nonpolar molecules, like lipids

  29. Fats • One type of lipids are triglycerides or fats. • Fats are made of glycerol with 3 fatty acids.

  30. Functions of Lipids • Key Point #4 • Fats and oils store energy long-term in living things. • (Other lipids have other functions) • Fat tissue also serve as cushioning and insulation. • Phospholipids make up the cell membrane. • Steroids and cholesterol can act as messengers.

  31. Nucleic Acids • Nucleic Acids are made of nucleotides. • DNA and RNA store genetic information. • Another name for nucleic acids are polynucleotides. • DNA is usually in a double helix shape; RNA is a single strand.

  32. Now it is time for Cold Calling

  40. Throw your whiteboards in the Air… Cellulose is an example

  41. Throw your whiteboards in the Air… Glucose is an example

  42. Throw your whiteboards in the Air… Hemoglobin is an example

  43. Throw your whiteboards in the Air… Function is short-term energy

  44. Throw your whiteboards in the Air… Function is to store genetic information

  45. Throw your whiteboards in the Air… It’s conformation determines its specific function

  46. Throw your whiteboards in the Air… Makes up cell membranes

  47. Throw your whiteboards in the Air… Are all nonpolar

  48. Worksheet time!
