I NEED HELP PLEASE I CANT FIND THE ANSWERS TO THESE LAST 3 QUESTIONS!!

If depolarizing membrane potentials open voltage-gated sodium channels, what closes them?

Why must a sushi chef go through years of training to prepare puffer fish for human consumption?

For action potential generation and propagation, are there any other cation channels that could substitute for the voltage-gated sodium channels if the sodium channels were blocked?

Voltage-gated ion channels open and close in response to membrane potential. Membrane potential is the difference in electrical potential between the interior and the exterior of a biological cell.
