Action potentials are all-or-none and self-regenerating events.These two properties contribute to which characteristic of action potentials? A) Each action potential will contribute to further membrane depolarization. B) Action potentials can travel faster in smaller axons. C) The activation and inactivation gates on Na⁺ channels open simultaneously. D) Action potentials are conducted without any loss of signal strength. E) Depolarization of the membrane causes voltage-gated Na⁺ channels to close, depolarizing the membrane even more.

The fact that action potentials are all-or-none and self-regenerating means that they are conducted without any loss of signal strength. This allows the action potential to propagate down the axon and reach the target cell with the same strength as the original signal.
