Sodium potassium pump action potential
The Sodium-Potassium Pump
The sodium-potassium pump uses energy in the form of ATP to move these ions against their concentration gradients and establish the “normal” intracellular ion concentrations. Set the sodium-potassium pump so that it is open to the inside of the cell. Record the initial concentrations of Na+ and K+in the data table on your answer sheet.

2. What role does the sodium/potassium pump (Na+/K+ pump) have in creating resting potential? 3. What happens to the inside of the cell when sodium ions flood into the cell? 4. After sodium ions have flooded into the cell and the sodium gates close, what happens to the potassium ions? 5. How does an action potential conduct along an axon? 6.

Action potential conduction down the axon involves passive current flow. TRUE. At the leading edge of the action potential, there is a capacitive current which is responsible for depolarizing the area of the membrane, allowing the activation of voltage gated channels and, in …

When the sodium gates shut and the potassium gates open, the membrane begins to return to its resting potential. This process of repolarization is finally completed when the sodium/potassium pump actively moves 3 - Na+ ions out of the cell for every 2 - K+ ions into the cell.
