Week 6 Lecture 1: Cell Physiology (Chapter 3) 1. Define: solution, solute, solvent, selective permeability, diffusion, concentration gradient, passive transport, active transport, electrochemical gradient, endocytosis, exocytosis, phagocytosis, receptor-mediated endocytosis, cell cycle, genome, chromosomes, chromatin, chromatid, DNA replication, metaphase plate, kinetochores, sister chromatids 2. Know what materials comprise the intracellular fluid and the interstitial (extracellular) fluid 3. What types of molecules can diffuse directly through the plasma membrane? 4. How do polar molecules get through the plasma membrane? 5. Is facilitated diffusion active or passive transport, and why? 6. Know the TWO types of gradients that affect ions specifically 7. Which is more positive, the interior or exterior of the cell? 8. Understand, explain, diagram the function of a sodium/potassium ion pump 9. Explain/diagram the different types of vesicular transport, its TWO functions, and give examples of each. 10. Know the difference between mitosis and cell division 11. Know, diagram, describe all stages of cell division 12. Know the four nucleotide base pairs and which other base pair each bonds to 13. Know what makes up the backbone of DNA strands 14. Diagram/explain DNA replication 15. What happens during interphase?.
