Sodium-Potassium Pump Mechanisms

The video explains the sodium-potassium pump, a type of active transport that moves sodium ions out of the cell and potassium ions into the cell using ATP. The process involves a carrier protein that changes shape to transport ions against their concentration gradient. The pump is crucial for maintaining electrolyte balance and proper nervous system function.

What is the primary function of the sodium-potassium pump?

• To move molecules from high to low concentration

• To move molecules from low to high concentration

• To balance pH levels in the cell

• To generate energy in the form of ATP

Why is the sodium-potassium pump considered active transport?

• It does not require energy

• It moves ions along the concentration gradient

• It requires energy in the form of ATP

• It only moves sodium ions

What ions are essential for proper electrolyte balance in the body?

• Calcium and Magnesium

• Sodium and Potassium

• Chloride and Phosphate

• Iron and Zinc

How many sodium ions are moved out of the cell in one cycle of the sodium-potassium pump?

• Three

• Five

• Two

• Four

What causes the carrier protein to change its shape during the sodium-potassium pump process?

• Splitting of ATP

• Binding of phosphate

• Release of potassium ions

• Binding of sodium ions

What happens to the carrier protein after it releases the sodium ions outside the cell?

• It changes shape again

• It releases ATP

• It binds with potassium ions

• It binds with more sodium ions

What is the ratio of sodium ions to potassium ions moved by the pump?

• 2:3

• 3:2

• 1:1

• 2:1
