A second nerve impulse cannot be generated until .
A)proteins have been resynthesized
B)the Na ions have been pumped back into the cell
C)the membrane potential has been reestablished
D)all sodium gates are closed

Question

Quizplus · Accepted Answer

The membrane potential must be reestablished, which involves the movement of ions across the membrane to restore the resting state of the neuron. This allows for the potential to reach the threshold for generating a new action potential. Options A and D are not accurate as proteins do not need to be resynthesized, and not all sodium gates need to be closed for a new impulse to be generated. Option B is partially correct, but it is the reestablishment of the membrane potential that allows for the movement of Na ions back into the cell, not the other way around.
