    Cellular Environment

    • The primary ion inside the cells is potassium (K+).

    Electrochemical Gradient

    • An electrochemical gradient in cells is created by the unequal distribution of ions across the cell membrane, resulting in a difference in electrical charge between the inside and outside of the cell.

    Physiological Processes Affected by Sodium-Potassium Pump

    • The sodium-potassium pump can affect various physiological processes, including:
      • Nerve impulse transmission and muscle contraction
      • Heart function and blood pressure regulation
      • Cellular volume regulation and water balance
