Active transport of sodium ions from the yeast cell

Abstract

It has been shown (Conway & Hingerty, 1948) that sodium ions which had entered muscle extensively in rats on a potassium-free diet were actively extruded on changing the animals to a potassium- rich diet. The mean half period of extrusion, even with the plasma potassium above the normal level within 24 hr. after the change, was about 3 days.
