1. The ATPase and phosphatase activities of red cell membranes were measured simultaneously as a function of the magnesium content of the medium. 2. It was found that when the magnesium concentration was greater than that of ATP, magnesium inhibited the ATPase and simultaneously stimulated the phosphatase. The concentrations of magnesium needed for half… CONTINUE READING
