In a typical mammalian neuron, what is the equilibrium potential of K+ ion (EK) at 37oC (Left answer), and why is the resting membrane potential close to EK(Right answer)?

Select one:

a. -80mV, Because neuronal membrane is mostly permeable to K+ at rest.

b. 62 mV, Because neuronal membrane is mostly permeable to Na+ at rest.

c. 123 mV, Because neuronal membrane is mostly permeable to Ca2+ at rest.

d. -65 mV, Because neuronal membrane is mostly permeable to Cl- at rest.
