Why might adding inorganic phosphate to a reaction mixture where glycolysis was 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 has 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.

Question

Quizplus · Accepted Answer

The metabolic intermediates of glycolysis are phosphorylated, meaning they contain phosphate groups. Adding inorganic phosphate to the reaction mixture would allow these intermediates to be replenished and sustain the metabolic pathway. This is because the phosphorylation of the intermediates is a crucial step in glycolysis and determines the direction and efficiency of the pathway.
