Phosphoenolpyruvate Phosphoenolpyruvate is the end-product produced by PEP carboxykinase. This enzyme requires GTP to function properly. Fructose-1,6-bisphosphate Fructose-1,6-bisphosphate is the substrate of fructose-1,6-bisphosphatase. This enzyme does not require GTP. Fructose-6-phosphate Fructose-6-phosphate is the end-product of fructose-1,6-bisphosphatase. this enzyme does not require GTP. Pyruvate Pyruvate is the substrate of pyruvate carboxylase. This enzyme does not require GTP. Biochemistry A researcher is studying the mechanisms of maintenance of glucose levels in rats. After a series of experiments in which he uses rat liver to measure enzyme activities, he notes that a the activity of a specific cytosolic enzyme involved in gluconeogenesis varies greatly with the concentration of cytosolic GTP. Which of the following is the end product produced by this enzyme? B General Principles 2020-10-28T01:54:48Z 2459150.5797222 WBR0861
