The "Threshold" Potential of a Membrane

The "threshold" potential of a membrane

A) is the point of separation from a living to a dead neuron.
B) is the lowest frequency of action potentials a neuron can produce.
C) is the minimum hyperpolarization needed to prevent the occurrence of action potentials.
D) is the minimum depolarization needed to operate the voltage-gated sodium and potassium channels.
E) is the peak amount of depolarization seen in an action potential.
