Verified Answer
Action potentials are characterized by which of the following?a)Depola...
During an action potential, the neuron undergoes a rapid and transient depolarization phase. This depolarization is caused by the opening of voltage-gated sodium channels, allowing the influx of sodium ions into the cell. This rapid depolarization is the key characteristic of an action potential.
Therefore, the correct answer is option C: Rapid depolarization.
