And on top of that, we have the hormones that stimulate this enzyme to transform phosphorase B into phosphorase A which automatically exists predominantly in the r state. And so we're going to break down glycogen much more readily into glucose to actually form ATP via glycolysis. Now, conversely, we can also have a high energy charge value. And what that means is we essentially have high ATP concentration relative to amp. And so under these conditions, our cells don't need to and don't want to produce ATP. And the ATP will actually act as an allosteric inhibitor.
