Part C
Which of the following occurs during repolarization?

   Voltage-gated potassium channels remain open and some voltage-gated sodium channels inactivate. Potassium flows into the cell.
   Voltage-gated sodium channels open. Sodium flows into the cell.
   Voltage-gated potassium channels open and potassium flows into the cell.
   Voltage-gated sodium channels open and some voltage-gated potassium channels inactivate. Sodium flows out of the cell.
   Voltage-gated potassium channels open and some voltage-gated sodium channels inactivate. Potassium flows out of the cell. (I think its this)
