Problem: Why do Na+ ions enter the cell when voltage-gated Na + channels are opened in neurons? a. because the Na+ concentration is much lower outside the cell than it is inside b. because the Na+ ions are actively transported by the sodium-potassium pump into the cell c. because the Na+ concentration is much higher outside the cell than it is inside, and the Na + ions are attracted to the negatively charged interior d. because the Na+ concentration is much higher outside the cell than it is inside, and the Na + ions are actively transported by the sodium-potassium pump into the cell
