And these ATP molecules can be quickly taken by the cell to basically contract those skeletal muscle tissues. And we also produce this amp molecule and it's this amp molecule that increases in concentration and that decreases the energy charge ratio and that causes the binding of the amp onto that phosphorptokinase to stimulate it to produce many more ATP molecules via the process of glycolysis. So under low ATP conditions the cell will use adenylate kinase to create ATP from two ATP molecules in a process that generates Amp and ATP relatively quickly and that allows the cells to basically continue contracting those actin myosin filaments. So let's summarize our result in the following overview in the following graph so we have the fructose six phosphate catalyzed by the phosphorchinas to produce this molecule not shown here. Then some number of processes take place and ultimately reproduce the ATP molecules and pyruvate. Now, when we're actually not exercising when we have lots of ATP molecules we don't want to produce the ATP molecules so they essentially go on and inhibit the activity of phosphorptokinase.
