Question

Quizplus · Accepted Answer

Maintaining ion gradients, particularly keeping sodium ions outside the cell, is a major energy-consuming activity for neurons. This is crucial for the neuron's ability to fire action potentials and is primarily achieved through the sodium-potassium pump, which uses ATP to transport sodium out of the cell and potassium into the cell, maintaining the necessary electrochemical gradients.
