Final answer:
K+ treatment results in potassium moving into cells because it stimulates the Na-K-ATPase, which transports K into the cell. When intracellular space is restored, the K shifts from extracellular to intracellular.
Step-by-step explanation:
Intracellular space, K+ treatment results in potassium moving into cells because it stimulates the Na-K-ATPase, which transports K into the cell. When intracellular space is restored, the K shifts from extracellular to intracellular.
The sodium-potassium pump system moves sodium and potassium ions against large concentration gradients. It moves two potassium ions into the cell where potassium levels are high, and pumps three sodium ions out of the cell and into the extracellular fluid.
