to determine the relative contributions of gluconeogenesis and glycogenolysis in a quantitative manner , we applied a new isotopic approach , using infusions of [ 6-3h ] glucose and [ 2-14c ] acetate to trace overall hepatic glucose output and phosphoenolpyruvate gluconeogenesis in 14 postabsorptive niddm subjects and in 9 nondiabetic volunteers of similar age and weight .
