     Indeed, every reaction step measured in the Na,K-ATPase reaction cycle was significantly affected by the concentration of cholesterol: the phosphoenzyme levels increased, the apparent ATP affinity increased, the cytoplasmic Na + activation was inhibited at high Na + concentrations, and the rate of phosphorylation and of spontaneous and K + -activated dephosphorylation increased[51 –53 ].
