Question
Sodium-potassium pump is one of the most important transport systems. If this pump suddenly stops working, what will happen?
- The environment will become hypotonic, and the cell will shrink.
- The environment will become hypertonic, and the cell will shrink.
- The environment will become hypotonic, and the cell will break.
- Nothing will happen.
Hint:
The cell will shrink if the environment is hypertonic. The cell will get bulged and lead to bursting if the environment is hypotonic.
The correct answer is: The environment will become hypotonic, and the cell will shrink.
- If the sodium-potassium pump stops, the ion concentration will be changed which leads to the change in membrane potential too.
- If the cell environment has more concentrated cells, the cell will shrink as it is in a hypertonic solution
- If the cell has more concentrated ions than the environment, the cell will become bulged and breaks after a point.
