How is gluconeogenesis regulated
Web29 okt. 2024 · Gluconeogenesis can be regulated by fructose 1,6-bisphosphatase. How is gluconeogenesis regulated? The rate of gluconeogenesis is ultimately controlled by the action of a key enzyme, fructose-1,6-bisphosphatase, which is also regulated through signal transduction by cAMP and its phosphorylation. Insulin counteracts glucagon by inhibiting ... Web5 mrt. 2024 · The most potent regulator of PFK-1 and FBPase-1, and therefore glycolysis and gluconeogenesis, is fructose 2,6-bisphosphate. Insulin and glucagon regulate glycolysis and gluconeogenesis through this molecule. Fructose 2,6-bisphosphate is produced from fructose 6-phosphate by a large enzyme with 2 catalytic domains.
