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.
E)an induced potential.

Question

Quizplus · Accepted Answer

An action potential occurs when neurotransmitters bind to receptors on a neuron, causing sodium ions to enter the neuron and change its electrical balance. This rapid influx of sodium ions depolarizes the neuron, leading to the propagation of an electrical signal along the neuron's membrane.
