Which statement about glycolytic kinases is FALSE? Reactions catalyzed by kinases in the first stage of glycolysis use ATP as the donor of the phosphate group, while in the second stage they use ADP as the acceptor of the phosphate group. Phosphofructokinase catalyzes the committed step of glycolysis in muscle cells. Allosteric regulation of liver pyruvate kinase depends on the energy charge of the cell. The expression of glycolytic kinases is controlled by the partial pressu of oxygen in tissues. All of the glycolytic reactions catalyzed by kinases are irreversible.
