BIO 1510 study guide for exam #2 3/3/08 For the exam on Monday, 3/3/08, you should be able to answer the following questions and perform the stated tasks. A. Transport across the cell membrane 1. Describe the structure of the plasma membrane, including the phospholipid bilayer (and its characteristics), and the  materials embedded in it. 2. Explain the fluid mosaic model of the bilayer – what characteristics make it “fluid”? 3. What are the functions of the various proteins embedded in the cell membrane? 4. Differentiate between peripheral and integral membrane proteins 5. What is meant by selective permeability?   6. What is the difference between passive and active transport?  What are the defining characteristics of each? 7. Define Brownian motion 8. Describe the processes of simple diffusion, facilitated diffusion, osmosis, primary active transport, coupled  transport, exocytosis, endocytosis, phagocytosis, and pinocytosis.  Be able to match each to a description 9. Differentiate between carrier proteins and channel proteins and describe the various types of each. 10. Where in the body does simple diffusion occur?  What gases are exchanged, and in what direction does each gas  diffuse? 11. Define osmotic pressure and hydrostatic pressure 12. Under what circumstances can the plasma become hypotonic / hypertonic, and what are the results of plasma  hypotonicity / hypertonicity to the blood cells? 13. Explain what happens to plant cells in isotonic, hypotonic, and hypertonic solutions  14. How do various cells maintain osmotic balance? B. Energy, enzymes, ATP, homeostasis & negative feedback 15. Name and state the two laws of thermodynamics 16. Define kinetic energy, potential energy, work, heat, calorie, metabolism, entropy, and enthalpy  17. Explain how automobiles and human cells are similar in their conversion of fuel into energy 18. Explain why oxidation and reduction are always coupled  19. Define free energy and state how free energy, and changes in free energy, can be calculated
