Movement of ions


The Na/K pump exchanges sodium and potassium ions against their concentration gradients using ATP to overcome this potential. This is particularly useful in the axons of nerve cells to 'reset' the nerve ready for firing the next impulse. It is also present in large numbers in the small intestine where it is used to drive the absorption of glucose (amongst other things).
