To maintain the cell's resting membrane potential,potassium's intracellular to extracellular ratio is important.

Question

Quizplus · Accepted Answer

The intracellular to extracellular ratio of potassium is important for maintaining the cell's resting membrane potential, as potassium ions play a major role in establishing this potential. The concentration gradient of potassium across the membrane determines the voltage across the membrane, so any changes in the intracellular or extracellular concentration of potassium will affect the resting membrane potential.
