Which pathway is primarily affected in glucose-6-phosphate dehydrogenase deficiency?
AGluconeogenesis
BGlycolysis
CPentose phosphate pathway
DBeta-oxidation
Which of the following statements correctly describes the effect of insulin and glucagon on gluconeogenesis?
AGlucagon decreases fructose 2,6-bisphosphate levels, stimulating gluconeogenesis.
BInsulin increases the levels of fructose 2,6-bisphosphate, which inhibits gluconeogenesis.
CInsulin acts through a kinase to promote glycolysis.
DFructose 2,6-bisphosphate is an activator of glycolysis.
Which of the following is not a substrate for gluconeogenesis?
ALeucine
BLactate
CPropionate
DGlycerol
