How would a chemical that prevents the opening of voltage-regulated Na+ channels affect the function of a neuron?
A)neuron will only be able to hyperpolarize
B)neuron will depolarize more rapidly
C)action potentials will lack a repolarization phase
D)neuron will automatically and repeatedly produce graded potentials
E)neuron will only be capable of producing graded potentials

Question

Quizplus · Accepted Answer

If voltage-regulated Na+ channels cannot open, the neuron cannot initiate action potentials, as these channels are crucial for the depolarization phase. The neuron will only be capable of producing graded potentials.
