Abstract
Endogenous concentrations of hexosemonophosphates and ATP decline sharply and rapidly in intact cells of Acer pseudoplatanus subjected to anoxia, whereas fructose-1,6-diphosphate and pyruvate accumulate markedly. In view of gas exchange data indicating an apparent acceleration of glycolysis under anoxic conditions, the observed changes in glycolytic metabolite concentrations indicate regulation of glycolysis by phosphofructokinase.
