Suppose you are a researcher examining the impacts of ion channels on resting membrane potential in typical neurons.By using a drug,you artificially open all sodium channels and keep all other ion channels closed.What value of the resting membrane potential should you observe?
A)-90 mV
B)-70 mV
C)0 mV
D)+30 mV
E)+62 mV

Question

Quizplus · Accepted Answer

The resting membrane potential will approach the equilibrium potential of sodium ions, which is approximately +62 mV, when only sodium channels are open.
