Role of bicarbonate generated by AIBCA in gluconeogenesis ll pathway. The conversion of CO2 to HCO3 − is catalyzed by β-CA, which is shown with a purple arrow. HCO3 − is a major element in conversion of pyruvate to oxaloacetate. Oxaloacetate is used to generate aspartate, citrate, and phosphoenolpyruvate through transamination, citric acid cycle, and gluconeogenesis pathways, respectively
