How many sodium ions get transported outside for every two Potassium getting into the cell?

The correct answer is Three.

Key Points

• The sodium-potassium pump is an essential mechanism in maintaining cellular homeostasis.
• For every two potassium ions (K⁺) transported into the cell, three sodium ions (Na⁺) are transported out of the cell.
• This pump is crucial for functions such as nerve impulse transmission and muscle contraction.
• The process utilizes ATP as an energy source to move ions against their concentration gradients.

Important Points

• The sodium-potassium pump is also known as Na⁺/K⁺-ATPase.
• Maintaining the correct balance of sodium and potassium ions is vital for cell function and volume.
