By decreasing the levels of this molecule, we decrease the levels of the reactant in this reaction. And that drives the rate of reaction five to the ground. And so we no longer are producing the urea and we're no longer generating the ornathan that we need for step number two, because in step number two, this carbon well phosphate combines with the ornithine to form the citrulline. And so ultimately, that's what causes high levels of ammonia and that's what causes hyperammenemia. Now, how do we treat a patient with this condition? Well, number one is we have to limit protein intake.
