WebGluconeogenesis is also stimulated by glucagon and inhibited by insulin (see “ Phosphofructokinase-2 ” for the mechanism). The table below shows the key steps of gluconeogenesis, which are irreversible and can only be bypassed with specific enzymes. WebThe problem for Gluconeogenesis was that the enzymes hexokinase and PFK were irreversible. So there are different enzymes (Fructose 1,6 bisphosphatase for PFK, and …
