Why might adding inorganic phosphate to a reaction mixture where glycolysis was rapidly proceeding help sustain the metabolic pathway?
A) It increases the energy level of the electrons that are transferred to the electron transport chain where ATP is produced.
B) It would increase the oxygen supply available for aerobic respiration because each phosphate group has four oxygen atoms as constituents.
C) The metabolic intermediates of glycolysis are phosphorylated.
D) It would increase the amount of glucose available for catabolism.

Question

Quizplus · Accepted Answer

The addition of inorganic phosphate would increase the phosphorylation of the metabolic intermediates of glycolysis, which would help sustain the metabolic pathway. This is because glycolysis relies on a series of phosphorylation reactions to generate ATP and the addition of phosphate would promote these reactions. Option A is incorrect because the addition of inorganic phosphate does not directly affect the energy level of electrons in the electron transport chain. Option B is incorrect because the addition of inorganic phosphate does not affect the oxygen supply available for aerobic respiration. Option D is incorrect because the addition of inorganic phosphate does not affect the amount of glucose available for catabolism.
