  1. Review Lecture II

  2. 3 pathways to degradation in the lysosome

  3. 3 possible fates of receptor proteins in an epithelial cell

  4. cholesterol is released in lysosome

  5. Glucose transporters can be stored in recycling endosomes

  6. 3 best understood protein sorting pathways in the trans Golgi network

  7. Intracellular signaling pathways

  8. 4 types of intercellular signaling

  9. 4 types of intercellular signaling

  10. Autocrine signaling allow a group of cells but not a single cell to respond to a differentiation signal coordinates decisions by a group of identical cells

  11. An animal cell depends on extracellular signals to survive or divide

  12. An animal cell depends on extracellular signals to differentiate. Without extracellular signals the cell will die

  13. Extracellular signaling molecules can bind to intracellular receptors

  14. Signaling molecules that bind to nuclear receptors are small and hydrophobic

  15. G-protein accepts GTP and disassemble into two active subunits

  16. Activation of gene transcription by cAMP

  17. Activation of gene transcription by cAMP

  18. Ca2+ and diacylglycerol activate protein kinase C

  19. Ras is activated by tyrosine kinase

  20. Tubulin heterodimer is the microtubule subunit

  21. Microtubule structure

  22. Structure of actin

  23. Growing and shrinking microtubules

  24. Model of intermediate filaments

  25. Polymerization of tubulin is nucleated by the γ-tubulin ring

  26. Model for actin filament nucleation by ARP complex

  27. Actin bundles in a microvillus

  28. Actin filament dynamics and platelet activation in

  29. Accessory proteins in a sarcomere

  30. Two membrane system that relays signal to contract muscle cells

  31. Ca2+ relieves tropomyosin blockage

  32. Attachment of dynein to cargo filled vesicle

  33. CdK activity can be suppressed by inhibitory proteins

  34. Assembly of pre-replicative complex during G1 phase

  35. Overview of cell cycle control system

  36. Caspase cascade occurs during apoptosis

  37. Mitogens stimulate G1-Cdk and G1/S-Cdk activities

  38. Cell growth like cell division is also stimulated by extracellular signals

  39. Summary of cell junctions found in the cell

  40. Summary of junctional and non-junctional adhesive mechanisms

  41. GAG and its core protein form proteoglycan

  42. Fibroblast surrounded by collagen fibrils
