Where is glycolysis stimulated by ADP? Phosphofructokinase is stimulated by AMP but not ADP because the concentration of ADP is not as variable as AMP.

All of the above because the glycolysis depends on these founding blocks to operate.

I think the keyword is "stimulate" usually ADP means low ATP concern so it will cause more ATP to produced. Hence stimulate Glycolysis for ATP production.

Phospho kinase 1 enzyme has about 4 active sites i.e active site for ATP, Citrate, AMP & Fructose 2-6 Bisphosphate site, Increase in Fructose 2-6 Bisphosphate (a very powerful stimulant of Phospho Kinase 1).

ATP & Citrate, signals Phospho Kinase 1 to Phosphorylate more Fructose 6 phosphate into Fructose 1-6 bisphosphate. In my opinion this is the Enzymatic Allosteric Regulation.

I agree ADP helps in stimulation of glycolysis as it results from phosphorylating the glucose compound.

What is mean by stimulant and allosteric?
