10. Phosphofructokinase 2 and.m fructose- 2,6-bisphosphatase have roles in both gluconeogenesis and glycolysis. Which of the following statements are true in regards to this enzyme? A. its activity will not be affected by hormonal signaling OB. it can act as a switch between gluconeogenesis and glycolysis OC. when phosphorylated phosphofructokinase 2 is more active and will make fructose-2,6-bisphosphate OD. an increased insulin to glucagon ratio will lead to the activation of fructose-2,6- bisphosphatase O E. phosphofructokinase 2 is allosterically modified by fructose-1,6-bisphosphate
