- During the final steps of glycolysis, 1,3-bisphosphoglycerate is converted to 3-phosphoglycerate and finally to phosphoenolpyruvate. What advantage would this strategy have for the cell?
Homework Answers
Glycolysis is sequential breakdown of a glucose molecule into 2
molecules of pyruvate. The process involves 10 steps. The final
steps of glycolysis involves substrate level phosphorylation in
which ATP(adenosine triphosphate) is generated.
ATP is the cellular energy currency of the cell. during the conversion of 1,3-bisphosphoglycerate to 3-phosphoglycerate, ATP is generated this process is catalyzed by phosphoglycerate kinase.
At the expense of carbon oxidation, ATP is generated from inorganic phosphate and ADP.. In total two molecules of ATP and two NADH generated during conversion of 1 molecule of glucose into two molecules of pyruvate. cell utilise the ATP produced during the last steps of glycolytic pathway in many energy requiring cellular processes.

1,3-bisphosphoglycerate is one of the two phosphoryl group donors in the synthesis of ATP during glycolysis. In human erythrocytes, the steady-state concentration of ATP is 2.24 mM, ADP is 0.25 mm, and 3-phosphoglycerate is 0.12 mm. Calculate the concentration of 1,3-bisphosphoglycerate at 25°C, assuming that the phosphoglycerate kinase reaction) is at equilibrium in the cell. (Standard delta G = -18.9).
