When neurotransmitters plug into the appropriate neuron receptors,sodium ions very briefly flood through potassium channels like water through dam floodgates.This changes the neuron's electrical balance and is called
A) an action potential.
B) an absolute refractory period.
C) a graded potential.
D) an anion.

Question

Quizplus · Accepted Answer

The influx of sodium ions through potassium channels is a key step in generating an action potential, which is a rapid change in the neuron's electrical potential that allows it to transmit signals to other neurons or muscles. Graded potentials are smaller changes in electrical potential that do not typically result in signal transmission. An absolute refractory period occurs after an action potential where the neuron cannot generate another action potential, but this is not related to the influx of ions through channels. An anion is a negatively charged ion and is not related to this process.
