Quizplus · Accepted Answer

The difference between the intracellular and extracellular levels of potassium is crucial for maintaining the resting membrane potential of cells, particularly neurons and muscle cells. This gradient is essential for the excitability of these cells, allowing them to respond to stimuli by generating action potentials. Pulse pressure, blood viscosity, and the amount of edema are influenced by other factors, not directly by the potassium gradient.
