So fructose six phosphates and this phosphorylates fructose six phosphate into fructose two six bisphosphate. And we actually spoke about fructose 26 bisphosphate in the previous lecture. So we saw that fructose 26 bisphosphate is actually an allosteric effector molecule that affects the activity of enzymes in glycolysis as well as gluconeogenesis. So if you don't remember what this does, go back to the previous lecture and check that out and notice this one is inactivated in state A. Now, when we go to state B, when protein kinase A phosphorylates the serial residue to form this phosphorylated state, we see that that deactivates this molecule, the PFK two, while activating that fructose bisphosphatase two. And what the fructose bisphosphatase two does is it basically reverses what this phosphorctocinase two actually does.
