Question

Quizplus · Accepted Answer

When the neuron is at rest, potassium's concentration gradient is mostly responsible for the movement of potassium ions out of the cell. This means that potassium ions will move from an area of high concentration inside the cell to an area of low concentration outside the cell. This movement is important to maintain the resting membrane potential of the neuron.
