A Common Feature of Action Potentials is That They

Question

A common feature of action potentials is that they
A)cause the membrane to hyperpolarize and then depolarize.
B)can undergo temporal and spatial summation.
C)are triggered by a depolarization that reaches the threshold.
D)move at the same speed along all axons.
E)require the diffusion of Na⁺ and K⁺ through ligand-gated channels to propagate.

Accepted Answer

Action potentials are triggered by a depolarization that reaches the threshold, which is the necessary level of depolarization required for the voltage-gated ion channels to open and initiate an action potential.
