The mechanism that allows many Na⁺ ions to move into the axon is A)negative feedback. B)positive feedback. C)equilibrium feedback. D)None of the choices are correct.

Question

Quizplus · Accepted Answer

The mechanism that allows many Na+ ions to move into the axon is positive feedback, as the influx of Na+ ions through voltage-gated channels depolarizes the membrane, which then opens more voltage-gated sodium channels, leading to further depolarization and more influx of Na+ ions. This feedback loop is essential for the propagation of action potentials along the axon. The other answer choices (A, C, D) do not accurately describe this mechanism.
