When one glucose molecule enters the glycolytic pathway, two molecules of pyruvate are created. This change in stoichiometry is ultimately due to the actions of: A. hexokinase, which phosphorylates the glucose molecule. B. phosphofructokinase-1, which creates a doubly-phosphorylated fructose molecule. C. aldolase, which cleaves the doubly-phosphorylated fructose molecule into two different 3-carbon molecules. D. triose phosphate isomerase, which catalyzes the rearrangement of bonds within one dihydroxyacetone phosphate molecule. E. phosphoglycerate kinase, which dephosphorylates two molecules of 1,3-bisphosphoglycerate.
