Final answer:
2-phosphoglycerate is indeed an intermediate in the glycolytic pathway, specifically in the energy-releasing pay off phase.
Step-by-step explanation:
Yes, 2-phosphoglycerate is an intermediate of the glycolytic pathway. In the pay off phase of glycolysis, following the investment of ATP in the priming phase, the 3-Phosphoglycerate produced from 1,3-bisphosphoglycerate is isomerized to 2-phosphoglycerate by the enzyme phosphoglycerate mutase.
This step is preparatory for the formation of phosphoenolpyruvate, another high energy molecule. Glycolysis is a central metabolic pathway involving a series of enzymatic reactions that convert glucose to pyruvate, yielding ATP and reducing power in the form of NADH.
