When a neurotransmitter opens a ligand-gated channel to an unknown ion+ and nochange in the membrane potential of â60 mV is observed, then the unknown ion+(assume that [K+]out=12 mM, [K+]in=120 mM, [Na+]out=140 mM, and [Na+]in=14 mM):
a. has a greater electrical than chemical potential
b. has a net outward flux
c. is at equilibrium
d. is in equal concentrations in and outside the nerve
e. is at a greater concentration outside the nerve than inside the nerve
