Question
What is the role of sodium pump?
- It exchanges extracellular Na+ with intracellular K+.
- It can stop by only metabolic toxins.
- It is ion passage.
- It is essential to maintain constant ion level.
Hint:
The main role of the sodium pump is to maintain constant ion concentration across the embrane.
The correct answer is: It is essential to maintain constant ion level.
- The sodium-potassium pump plays an important role in maintaining the ion concentration.
- They are active for keep the higher concentrations of potassium inside and sodium outside the cells.
- The main role of the sodium pump is to keep ion concentration balanced.
