Why do tumor cells have a high aerobic glycolysis?

Authors


Abstract

In Ehrlich ascites cells and several other tumors, the high aerobic glycolysis is maintained by generation of ADP and Pi by the plasma membrane Na+K+ ATPase. The high ATPase activity is caused by a defective pump that operates at a low efficiency. Studies of the mechanism of action of the Na+K+ ATPase and other pump ATPases suggest several alternative mechanisms that might account for the decreased efficiency. The possibility of involvement of a proteolipid is under investigation.
