1. If you used the voltage clamp to determine the peak Na current at a membrane potential of -10 mV, how would you then calculate the peak Na conductance?

2. The K+ current increases as the membrane potential is clamped at increasingly positive potentials? One reason for this is that increasing activation of voltage-dependent K channels results in an increase in gK. What is the other reason?

5) A new drug has been discovered that completely opens the voltage-gated potassium channels. If this drug is used experimentally on an isolated axon, the membrane potential can be easily measured. Assume that this experiment provided the following results. The extracellular Na+ is 145 mM and the extracellular K+ is 4mM, the measured membrane potential in the presence of the drug is -94mV. Using this information, calculate the intracellular K+ concentration. To solve this equation, you will need to use...
