Which of the following is TRUE regarding the absolute and relative refractory periods of the action potential (AP)? A. The absolute refractory period may be overcome if enough excitatory stimulation is applied to the neuronal membrane. B. The absolute refractory period is due the closing of the activation gate of voltage gated sodium channels at the peak of the AP. C. The relative refractory period is due to the closing of the activation gate of voltage gated potassium channels during the overshoot phase of the AP. D. The relative refractory period is due the closing of the inactivation gate of voltage gated sodium channels . E. All of the above statements are FALSE.

C. The relative refractory period is due to the closing of the activation gate of voltage gated potassium channels during the overshoot phase of the AP.
D. The relative refractory period is due the closing of the inactivation gate of voltage gated sodium channels .
E. All of the above statements are FALSE.
The relative refractory period is that the interval of your time throughout that a second action potential will be initiated, however, initiation would force a greater stimulation than before.
