← ScienceWhich unintended outcome occurs when a neuron's sodium channels activate improperly during repolarization?
A)Sustained elevated action potential threshold
B)Premature return to resting membrane potential
C)Prolonged refractory period due to inactivation✓
D)Increased neurotransmitter reuptake efficiency
💡 Explanation
Sodium channel malfunction during repolarization causes prolonged refractory period due to inactivation because the channels remain closed longer, therefore preventing immediate reactivation rather than allowing the neuron to fire another action potential immediately.
