Sample Questions

1

Which pathway is primarily affected in glucose-6-phosphate dehydrogenase deficiency?

AGluconeogenesis

BGlycolysis

CPentose phosphate pathway

DBeta-oxidation

2

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.

3

Which of the following is not a substrate for gluconeogenesis?

ALeucine

BLactate

CPropionate

DGlycerol
