Describe three different mechanisms of cell signaling base on time scales. 2. When we record an electroencephalogram (EEG), what part of body do we record from? 3. In a hypothetical cell we find the following distributions of ions. You are told that the cell is in electrochemical and osmotic equilibrium. Both sodium and chloride are freely membrane permeable. Potassium and Bromide are membrane impermeable. Fill in the blanks and for each step explain how you did it. 4. In a typical mammalian cell, what’s the major ion composition of ICF & ECF? Are all of the ions membrane-permeable? 5. What is the major component of the cell membrane? What are its unique properties? 6. List 4 movements of lipid within lipid bilayers. Which one is the rarest event? 7. Are the compositions of lipid bilayer identical in different type of cells? Give me an example. 8. Describe the structure and function of cholesterol. 9. Name two kinds of lipid which distribute asymmetrically in cell membrane and where are they in the bilayer. 10. What are the factors determining relative permeability of lipid bilayer? 11. Describe four types of transportation across the cell membrane. Are they passive or active transport? 12. What kind of transport exhibits saturation kinetics (Vmax)? 13. How does a Glucose/Na+ co-transporter move glucose against its osmotic driving force? 14. Describe the function of Na+-K+ pump. 15. Name three amino acids, one with a negative side chain, a second with a positive side chain, and the third with a nonpolar side chain. 16. Where do usually find polar side chain amino acids in a folded membrane protein? 17. In general, how many amino acids do we need to form an alpha-helix that can cross a membrane? 18. Based on the hydropathy plot below, how many trans-membrane fragments are in this protein?...
