Why might adding inorganic phosphate, to a reaction mixture where glycolysis is rapidly proceeding, help sustain the metabolic pathway?

A) It would increase the amount of glucose available for catabolism.
B) It would increase the oxygen supply available for aerobic respiration because each phosphate group contains four oxygen atoms as constituents.
C) The metabolic intermediates of glycolysis are phosphorylated.
D) It increases the energy level of the electrons that are transferred to the electron transport chain where ATP is produced.


C) The metabolic intermediates of glycolysis are phosphorylated.
