Question

Quizplus · Accepted Answer

The ion with the largest concentration inside a human cell is potassium (K+). This is because potassium is involved in many cellular processes, including maintaining the cell's resting membrane potential, regulating fluid balance, and facilitating enzyme activity. Additionally, the high concentration of potassium inside cells is maintained by the sodium-potassium pump, which actively transports potassium ions into the cell and sodium ions out of the cell.
