It transforms the fructose six phosphate into the fructose one six bisphosphate which is committed to that step. And this is our enzyme that catalyzed that step. Now, let's remember how skeletal muscle cells actually regulate this enzyme. So they use ATP and ANP molecules so let's suppose we have a high energy charge in the cell and what that means is we have a high ratio of ATP to amp. Remember, energy charge simply means the ratio of ATP to amp. Now if we're resting this is basically what we're going to have.
