Presentation Transcript

  1. Grinnell How biological research differs From a history class

  2. Electron Micrographs: What can we see and tell? CBI Liver Cell ‘View 4’ CBI Liver Cell ‘View 5’ Why Cell Biology is Different From Histology

  3. Live images: What can we see? CBI 1.1: Dancing Keratocyte What do these two approaches tell us about cells their properties and their components?

  4. Biological Membranes A) Where are they found? B) What are their functions? C) What are their major components?

  5. Lipids All lipids have same general chemical structure: polar head group and nonpolar hydrocarbon tails Types of lipids? Types of lipids in biomembranes? Fig 10-2 see also CBI 10.2

  6. Cholesterol Fig 10-10: CBI 10-2

  7. How do lipids form membranes? Combination of shape and packing Role of hydrocarbon tails?

  8. What is the role of cholesterol?

  9. Why is the structure of a biological membrane important? Fig 10-14 Why is a biological membrane more similar to a house than it is to a fence? (Think about on break)

  10. Proteins What is a protein? (in general terms) What functions do they perform? What else is in biological membranes?

  11. Membrane Proteins Transmembrane/Integral or Peripheral What functions would require each category of membrane protein?

  12. Covered: Biological membranes where they are found their chemical components how the components are arranged properties and functions of membranes

  13. Next: Membrane dynamics: Fluid Mosaic Model Lipid Rafts Types and functions of organelles Introduction to Graves’ Disease
