3. In scenario 3, all the parameters are the same as scenario 1, except that relative chloride permeability is increased from a value of 10 for scenario 1 to a value of 1000 for scenario 3. 1. 2. 3. a) Calculate the equilibrium potential for chloride (in millivolts) for scenario 3. b) Calculate the membrane potential in millivolts for the cell in scenario 3 c) Compared to scenario 1, is the membrane potential of the cell in scenario 3 the same, depolarized, or hyperpolarized relative to the cell in scenario 1. (Select one of these choices.) d) Calculate the delta free energy value of chloride for scenario 1 and scenario 3. Use this information to describe why the membrane potential in scenario 3 is the same, depolarized, or hypolarized relative to scenario 1. 4. In scenario 4, all the parameters are the same as scenario 1, except that relative chloride permeability is increased from a value of 10 for scenario 1 to a value of 1000 for scenario4. However, unlike the case for scenario 3, the intracellular chloride concentration is reduced from 10 mM to 3.2 M; 1. 2. 3. a) Calculate the equilibrium potential for chloride (in millivolts) for scenario 4. b) Calculate the membrane potential in millivolts for the cell in scenario 4 c) Compared to scenario 1, is the membrane potential of the cell in scenario 4 the same, depolarized, or hyperpolarized relative to the cell in scenario 1. Select one of these choices. d) Calculate the delta free energy value of chloride for scenario 4. Use this information to describe why the membrane potential in scenario 3 is the same, depolarized, or hypolarized relative to scenario 1.
