Which of the following best describes a difference between the voltage-gated and leaky potassium channels?
A) The voltage-gated channels are always open, while the leaky channels only open during action potentials.
B) The voltage-gated channels only open when there is a lot of potassium in the cell, while the leaky channels are always open.
C) The voltage-gated channels ensure the cell is ready for future action potentials, while the leaky channels ensure chloride and potassium ions are at an equilibrium.
D) The voltage-gated channels open when the cell becomes positively charged, while the leaky channels maintain the cell's resting potential.
