Gluconeogenesis Flashcards
Gluconeogenesis Reaction
2 Pyruvate + 4 ATP + 2 GTP + 2NADH –> glucose + 4 ADP + 2 GDP + 2 NAD
(some amino acids, lactate –>) pyruvate –> oxaloacetate
pyruvate carboxylase, use 1 ATP
(some amino acids –>) oxaloacetate –> phosphenolpyruvate
PEP carboxykinase, use 1 GTP
fructose 1,6-bisphosphate –> fructose 6-phosphate
fructose 1,6-bisphosphatase
glucose 6-phosphate –> glucose
glucose 6-phosphatase
pyruvate carboxylase inhibition
insulin
PEP carboxykinase inhibition
insulin, AMP
PEP carboxykinase stimulation
glucagon, cAMP
fructose 1,6-bisphosphatase inhibition
fructose 2,6-bisphosphate, AMP
fructose 1,6-bisphosphatase stimulation
citrate, main regulation step
glucose 6-phosphatase inhibition
insulin
glucose 6-phosphatase stimulation
glucagon
