How would the absolute refractory period be affected if voltage-regulated sodium channels failed to inactivate?
A) It would last indefinitely.
B) It would be much briefer.
C) It would be basically unaffected.

The failure of voltage-regulated sodium channels to inactivate means that there would be a constant influx of sodium ions, which would make it impossible for the membrane potential to return to its resting state. As a result, the absolute refractory period would last indefinitely.
