If the sodium/potassium ion pump were to stop functioning, what would eventually happen to the concentration gradients of sodium and potassium ions across the membrane

The correct answer would be - concentration gradient will reach to equilibrium.

Explanation:

If the Na+/K= ion pump stops working which is to pump the sodium and potassium ion across the cell membrane. The movement takes place in 3:2 ratio with the help of ATP.

Eventually, the concentration gradients of sodium and potassium would be equal and found equilibrium across the membrane. This equilibrium would be reached due to passive transport that occurs in either direction across the membrane.
