Below is the mechanism for the enzyme enolase, which converts 2-phosphoglycerate to phosphoenolpyruvate.
Below is the mechanism for the enzyme enolase, which converts 2-phosphoglycerate to phosphoenolpyruvate. C. What is the significance of producing phosphoenolpyruvate considering that a major goal of glycolysis is to produce ATP? What is the name for this process? Which enzyme in glycolysis performs this reaction and what is its DG´˚? Recall: phosphoenolpyruvate + H2O à Pi + […]
