Sept 6 (biomolecules carbs nuc-acid)

  1. 1. Biology I: Introduction to Bio-molecules Mr. Nettles
  2. 2. Agenda-Tuesday, Sept. 6, 2011 <ul><li>Warm-Up – 5 min </li></ul><ul><li>Lesson – 30 min </li></ul><ul><li>Wrap-Up – 5 min </li></ul><ul><li>Cell Projects (due Fri.) – 20 min </li></ul>
  3. 3. Today’s Objectives <ul><li>I will identify and distinguish between the four major groups of bio (organic) molecules. </li></ul><ul><li>I will define the words: monomer and polymer. </li></ul><ul><li>I will articulate five key things about carbohydrates and nucleic acids. </li></ul>
  4. 4. Warm-Up <ul><li>What organelle is responsible for producing energy within a cell? </li></ul><ul><li>What plant cell organelle uses sunlight to make cellular food and store energy? </li></ul><ul><li>What animal cell organelle helps transfer chromosomes during Meiosis and Mitosis? </li></ul>
  5. 5. Bio (organic): Molecules: Has to do with life Makes up everything Bio (organic) molecules make up EVERYTHING in a cell
  6. 6. <ul><li>Organic molecules are polymers </li></ul>Monomer Mono: one mer: molecule Monomer: one part that makes up a polymer Polymer Poly: many mer: molecule Polymer: a large molecule made of many repeating parts
  7. 7. Think! <ul><li>What is something you see everyday that is made of many repeating parts? </li></ul>
  8. 8. Monomer or Polymer?
  9. 11. A single part
  10. 12. Many repeating parts
  11. 13. There are 4 major groups of bio (organic) molecules: carbohydrates, nucleic acids, proteins & lipids
  12. 14. For each (bio) organic molecule, you NEED to know 5 things! <ul><li>AKA (other names): other names it can be called </li></ul><ul><li>Monomer: name of the monomer </li></ul><ul><li>Purpose: job in our bodies </li></ul><ul><li>Examples: things that are that organic molecule </li></ul><ul><li>Related organelles: what organelle it has to do with </li></ul>
  13. 15. Carbohydrates <ul><li>AKA: Sugar, polysaccharide, glucose </li></ul>
  14. 16. Carbohydrates <ul><li>AKA: Sugar, polysaccharide, glucose </li></ul><ul><li>Monomer: Monosaccharide </li></ul><ul><li>(simple sugar) </li></ul>
  15. 17. Carbohydrates <ul><li>AKA: Sugar, polysaccharide, glucose </li></ul><ul><li>Monomer: Monosaccharide (simple sugar) </li></ul><ul><li>Purpose: store energy </li></ul>
  16. 18. Carbohydrates <ul><li>AKA: Sugar, polysaccharide, glucose </li></ul><ul><li>Monomer: Monosaccharide </li></ul><ul><li>Purpose: Storage of energy and provide structure </li></ul><ul><li>Examples: starch, cellulose, glucose (suffix ‘ose’) </li></ul>
  17. 19. Carbohydrates <ul><li>Related organelles: </li></ul><ul><ul><li>- Mitochondria : uses carbohydrates (sugar) to make energy </li></ul></ul>-Chloroplast: uses CO 2 and sunlight to make carbohydrates (sugar)
  18. 20. Carbohydrates Think! <ul><li>What are the monomers of carbohydrates called? </li></ul><ul><li>Give one example of a carbohydrate. </li></ul>
  19. 21. Nucleic Acids <ul><li>AKA: DNA, RNA </li></ul>Nucleic acid
  20. 22. Nucleic Acids <ul><li>AKA: DNA, RNA </li></ul><ul><li>Monomer: Nucleotide </li></ul>
  21. 23. Nucleic Acids <ul><li>AKA: DNA, RNA </li></ul><ul><li>Monomer: Nucleotide </li></ul><ul><li>Purpose: carry genetic information </li></ul>
  22. 24. Nucleic Acids <ul><li>AKA: DNA, RNA </li></ul><ul><li>Monomer: Nucleotide </li></ul><ul><li>Purpose: carry genetic information </li></ul><ul><li>Examples: DNA, RNA </li></ul>
  23. 25. Nucleic Acids <ul><li>Related organelles: </li></ul><ul><ul><li>- Nucleus : stores DNA </li></ul></ul>
  24. 26. Nucleic Acids Think! <ul><li>What are the monomers of nucleic acids called? </li></ul><ul><li>Give one example of a nucleic acid. </li></ul>
  25. 27. Carbohydrates, Nucleic Acids or neither?
  26. 29. Amino Acids
  27. 30. Monosaccharides
  28. 32. Does the work of the cell (makes and stores energy)
  29. 33. Starch
  30. 34. Carry genetic information
  31. 36. Nucleotides
  32. 37. Glucose
  33. 38. DNA and RNA
  34. 39. Fats and Oils
  35. 40. Energy Storage
  36. 42. Wrap-Up <ul><li>Give two examples of nucleic acids. </li></ul><ul><li>What is the difference between a monomer and a polymer? </li></ul><ul><li>Starch and glucose are examples of _________. </li></ul>
