I have a test on friday and its over my least favorite subject... metabolism, bleh! so anyone with a good knowledge base out there in this topic?

I may have some questions later, that i will post on here... Ill start it off with one..
*in the liver
With PFK-2 regulating PFK-1, and PFK-2 (Fructose 2,6 bis P is phosphorylated) by insulin (well techincally PKA, but thats a 2nd messanger) it acts as an allosteric activator of PFK-1. But when it is dephosphorylated by glucagon the Fructose goes back to Fructose-6P does the fructose then go through the PFK-1 reaction resulting in Fructose 1,6 bisP and continuing down the cascade? or since Fructose26bisP is low, that it stays there which is then only stimulated by AMP? I know when it(F26BP) goes down that stimulates glyconeogensis, does it reverse its path and go back to glucose?
