Question
In the Cori cycle, when glucose is degraded by glycolysis to lactate in muscle, the lactate is excreted into the blood and returns to the liver where it is converted back into glucose by gluconeogenesis. Sort the following list of enzymes into those that are involved in •both glycolysis (including lactate formation) and gluconeogenesis, •glycolysis of glucose to lactate only, •gluconeogenesis only, or •neither pathway.

hexokinase
Enzymes involved only in glucogenesis from lactate
pyruvate carboxylase
fructose 1,6-bisphosphatase
Enzymes involved in neither glycolysis nor glucogenesis
alcohol dehydrogenase
glyceraldehyde 3-phosphate
lactate dehydrogenase
