BIPN 100 F15 (Kristan) Problem-solving #6 answers

The Chord Conductance equation: (a) simplifies to the Nernst equation if a membrane is permeable to a single type of ion (e.g., the Chord Conductance equation for K+ is the Nernst equation for K+ if there are only K+ channels open.) (b) can explain Vrest. (c) allows us to calculate the driving force for each type of ion that contribute to a multi-ionic current. (d) can also be used to calculate the reversal potential for the NMJ EPSP if the ratio of Na+ and K+ conductances are known.
