Abstract

This chapter discusses the effect of internal adenine nucleotides on sodium pump-catalyzed Na–Na and Na–K exchanges. Na–K exchange is a saturating function of internal ATP. An increase in the concentration of ADP and ATP held constant, there is a sharp decrease in Na–K exchange. The inhibition by ADP is dependent on the ATP concentration because the ADP effect diminishes with increasing ATP concentrations. On the other hand, Na–Na exchange depends on the concentration of ADP. However ADP activation is independent of the ATP concentration.
