Which of the following is NOT true of nicotinic-gated channels?
A)The binding of ACh allows diffusion of both Na+ into and K+ out of the neuron.
B)Only EPSPs are generated.
C)Only action potentials are generated.
D)Summation can occur because of a graded response.

Quizplus · Accepted Answer

Nicotinic-gated channels generate excitatory postsynaptic potentials (EPSPs), not action potentials directly. Action potentials are generated if the EPSPs summate to reach the threshold at the axon hillock.
