← ScienceWhich mechanism hinders charge propagation across a neuron's axon?
A)Axonal membrane capacitance✓
B)Sodium-potassium pump failure
C)Mitochondrial ATP depletion
D)Microtubule depolymerization rates
💡 Explanation
Axonal membrane capacitance opposes changes in membrane potential because capacitive current increases. Therefore this hinders rapid changes in axon voltage along its length, rather than ion pump failure, which inhibits resting potential.
