[Mechanism of changes in the rate of glycolysis and levels of ATP and 2,3-diphosphoglycerate in human erythrocytes during aging].

Reasons which have induced changes in the glycolysis rate, ATP and 2,3-diphosphoglycerate content in human erythrocytes with ageing are studied. A fall of the hexokinase activity is shown to be one of the reasons of a significant decrease in the glycolysis rate. The total ATPase activity in erythrocytes does not change with the age. At the same time the decay rate of 2,3-diphosphoglycerate increases, that, evidently, is one of the reasons of the 2,3-diphosphoglycerate content decrease in erythrocytes with ageing.
