Question

Quizplus · Accepted Answer

Energy in the form of ATP is primarily required to maintain a nerve cell membrane at resting potential. This is achieved through the action of the sodium-potassium pump (Na+/K+ ATPase), which actively transports sodium ions out of the cell and potassium ions into the cell, against their concentration gradients, using ATP as an energy source. This process is crucial for maintaining the electrochemical gradient across the cell membrane, which is essential for the resting potential of nerve cells.
