Transcript of Sept 7 (biomolecules lipids proteins)

  • 1.Biology I: Introduction toBio-moleculesMr. Nettles

2. Agenda-Wed., Sept. 7, 20111. Warm-Up 5 min2. Lesson 30 min3. Wrap-Up 5 min4. Cell Projects (due Fri.) 20 min 3. Todays Objectives I will identify and distinguish between the four major groups of bio (organic) molecules. I will articulate five key things about lipids and proteins. 4. Warm-Up1. What is the monomer of a nucleic acid?2. What two organelles are related tocarbohydrates ?3. This an example of a___________.A. Sugar B. Protein C. Nucleic Acid 5. For each (bio) organic molecule, you NEED to know 5 things!1.AKA (other names): other names it can becalled2.Monomer (building block): name of themonomer3.Purpose (what it does): job in our bodies4.Examples: things that are that organicmolecule5.Related organelles: what organelle it has todo with 6. Lipids AKA: Fats, oils, waxes 7. Lipids AKA: Fats, oils, waxes Monomer: fatty acid 8. Lipids AKA: fats, oils, waxes Monomer: fatty acid Purpose: form boundaries (makes up the cell membrane!) 9. Lipids AKA: Fats, Oils, Waxes Monomer: Fatty Acid Purpose: form boundaries (makes up thecell membrane!) Examples: lard, vegetable oil 10. Lipids Related organelle: -Cell/Plasma membrane: made of lipids! 11. LipidsThink! What are the monomers of lipids called? Give one example of a lipid. 12. Proteins AKA: enzymes, polypeptides Enzymes make up a significant part of the cellmembrane in living organisms. 13. Proteins AKA: enzyme, polypeptide Monomer: Amino Acid 14. Purpose: What do proteins do? Some control the rate of reactions and regulate cell processes. Some are used to form bones and muscles. Others transport substances into or out of cells to help fight diseases. 15. Proteins AKA: enzyme, polypeptide Monomer: Amino Acid Purpose: Do the work of the cell !! 16. Proteins AKA: enzyme, polypeptide Monomer: Amino Acid Purpose: Do the work of the cell !! Examples: enzymes, lactase, hemoglobin, insulin (suffix ase) 17. Proteins Related Organelle:-Ribosome: makes proteins! 18. ProteinsThink! What are the monomers of proteins called? Give one example of a protein. 19. Carbohydrates, Nucleic Acids,Lipids, or Proteins? 20. Amino Acids 21. Form Boundaries 22. Monosaccharides 23. Does the work of the cell- carries out different cell functions like fighting disease and transporting substances in and out of the cell 24. Starch 25. Carry genetic information 26. Lactose 27. Nucleotides 28. DNA and RNA 29. Fats and Oils 30. Energy Production and Storage 31. Polypeptides 32. Lactase 33. Cell Membrane 34. Wrap-Up1. What is the monomer of a lipid?2. Give two examples of proteins?3. Phosphatase is a __________.A. Lipid B. Protein C. Sugar
