by analyzing glucose production rates as a function of corresponding concentrations of extracellular pyruvate , cytosolic oxalacetate , and cellular 3-phosphoglycerate in the presence and absence of hormones and assuming no primary activation of phosphoenolpyruvate carboxykinase , estimates were made of the relative contributions of stimulation of formation of cytosolic oxalacetate and inhibition of pyruvate kinase to hormonal stimulations of gluconeogenesis .
