Unformatted text preview: What happens if you then add NaCl to one side only? 6. Explain the meaning of hyperpolarization vs. depolarization. 7. Distinguish between permeability and conductance. 8. What is meant by electrochemical equilibrium? 9. Write the Nernst equation. Explain how it can be used to determine the equilibrium potential for K + . What good is it to know the K + equilibrium potential? Predict the potassium equilibrium potential under the following conditions: [K + ] o = 100 mM, [K + ] i = 5. R = 8.3 coulomb volts/deg mole; T = 298 K, F=96,500 coul/mol. 10. Name 3 types of ion channels, distinguished by their mode of activation. 11. Describe a condition in which ions move through ion channels against their concentration gradient. 12. What is “driving force” for movement of ions through a channel?...
