The asthma and COPD drug salbuterol is sometimes administered in an emergency to lower the blood levels of this substance. The antibiotic valinomycin selectively complexes with this substance. The normal range of serum values for this ion is 3.5 to 5 millimoles. "Peaked" T waves, followed by the loss of P waves and the appearance of a "sine wave" morphology, occur on an EKG of patients with high blood levels of this ion. Aldosterone (*) increases the rate of secretion of this ion in the collecti

"Peaked" T waves, followed by the loss of P waves and the appearance of a "sine wave" morphology, occur on an EKG of patients with high blood levels of this ion. Aldosterone (*) increases the rate of secretion of this ion in the collecting duct of the kidney. The reversal potential of this ion is -80 mV ["millivolts"], just below a neuron's resting potential. Two of these ions are pumped in and three of a lighter ion are pumped out in a common ATPase. For 10 points, name this alkali metal ion exchanged with sodium in a common pump.
