Where should most of the potassium ions be located when a muscle cell is at rest?

Question

Quizplus · Accepted Answer

Most of the potassium ions should be located in the cytosol of the muscle cell when it is at rest. This is due to the action of the sodium-potassium pump, which actively transports potassium ions into the cell and sodium ions out of the cell, thus maintaining a higher concentration of potassium ions inside the cell compared to outside.
