Final answer:
During the absolute refractory period, the voltage-gated Na+ channels are inactivated and cannot open or generate another action potential.
Step-by-step explanation:
During the absolute refractory period, the voltage-gated Na+ channels are inactivated, meaning they cannot open or generate another action potential. The inactivation gate of these channels is closed, preventing their activation. This prevents the influx of Na+ ions and the generation of another action potential during this period.
