  2. Ruptured cell wall.

  3. Scanning electron micrograph showing a prostate cancer cell immediately after exposure to ultrasound. Image has been color enhanced to show to the spot where the cell membrane has been removed. Image courtesy of Robyn Schlicher, Robert Apkarian and Mark Baran

  4. Scanning electron micrograph of E. hirae.

  5. E. Coli (colored)

  6. Ostrich Egg Cytokinesis

  7. Rat Hippocampal Neuron

  8. Human egg cell. Red Blood Cell

  9. Mucous secreting goblet cell in trachea. themodulator.org/archives/Trachea.jpg

  10. MEMBRANEBOUND PROTEINS K+ Channel Na/K ATPase

  11. MEMBRANEBOUND PROTEINS Enzymes ATP Synthase-Uses concentration gradient to ADP+P ATP

  12. Receptors MEMBRANEBOUND PROTEINS In the brain-Adrenaline In the body- Insulin

  13. oligosaccharide groups cholesterol phospholipid EXTRACELLULAR ENVIRONMENT (cytoskeletal pro-teins beneatch the plasma membrane) open channel protein gated channel protein (open) gated channel protein (closed) active transport protein RECEPTOR PROTEIN ADHESION PROTEIN RECOGNITION PROTEIN (area of enlargment) TRANSPORT PROTEINS CYTOPLASM PLASMA MEMBRANE Fluid mosaic model of plasma membrane Functions of transmembrane proteins: enzymes, transport, receptors, recognition, etc.

  14. NOT Cells!!!

  15. How do you organize them

  16. Archae -Single cell -Cell wall -Special Membrane -No Nucleus -Can make energy from inorganic molecules Bacteria -Single cell -Cell wall or not -Photosynthesis or not -Special covering -No Nucleus -Can be pathogenic
