All the following enzymes catalyze physiologically irreversible reactions of glycolysis except
assistant
The correct answer is  GLYCOLYSIS IS REGULATED AT THREE STEPS INVOLVING NONEQUILIBRIUM REACTIONS Although most of the reactions of glycolysis are freely reversible, three are markedly exergonic and must, therefore, be considered to be physiologically irreversible. These reactions, catalyzed by hexokinase (and glucokinase), phosphofructokinase, and pyruvate kinase, are the major sites of regulation of glycolysis. Reference: Harper; 30th edition; Page no: 172
