Following a high carbohydrate meal, conversion of fructose-6-phospahte to fructose-1,6-bisphosphate will be catalyzed by:
a. phosphofructokinase-2, which is activated when insulin causes dephosphorylation of phosphofructokinase-1
b. phosphofructokinase-1, which is activated when insulin causes dephosphorylation of phosphofructokinase-2
c. phosphofructokinase-1, which is activated when insulin causes phosphorylation of phosphofructokinase-2
d. phosphofructokinase-1, which is activated when glucagon causes phosphorylation of phosphofructokinase-2
e. phosphofructokinase-2, which is activated when epinephrine causes phosphorylation of phosphofructokinase-1
