Nicotinic acetylcholine receptor is an ionotropic receptor that opens in response to
acetylcholine, and passes a combination of K+ and Na+ currents. A postsynaptic neuron
has a resting membrane potential of -70mV and the Na+ equilibrium potential of 0mV.
This postsynaptic neuron expresses nicotinic acetylcholine receptors. When the neuron
presynaptic to the postsynaptic neurons was stimulated (and release acetylcholine into
synaptic cleft), _______________ (species of ion) _______________ (net movement of
ion) and ______________ the membrane potential. This change in membrane potential
is called ___________.
a. Na+, flows out of, depolarize, IPSP
b. K+, flows out of, hyperpolarize, IPSP
c. Na+, flows into, depolarize, EPSP
d. K+, flows into, depolarize, EPSP
e. Na+, flows into, depolarize, EPSP
