Final answer:
If the Na+/K+ pump is inhibited and no ATP is present in a cell, the pump will remain facing the extracellular space with sodium ions bound. As a result, the cell will not be able to maintain the proper balance of sodium and potassium ions.
Step-by-step explanation:
The sodium-potassium pump is a vital mechanism in maintaining the electrochemical gradient and ion concentrations in living cells. If the Na+/K+ pump is inhibited and no ATP is present in a cell, the pump will remain facing the extracellular space with sodium ions bound. This means that the pump will not be able to perform its function of moving sodium ions out of the cell and potassium ions into the cell. As a result, the cell will not be able to maintain the proper balance of sodium and potassium ions.
