We have three ATPs and an aspartape. So two ATPs are used here and one ATP is used here and we generate urea. Two ATPs, we have an amp, we have an orthophosphate, Pyrophosphate and fumarate. And as I said before, because we have the Pyrophosphate and it basically breaks down that's equivalent to using one more ATP. And so instead of having three total, we have four equivalent ATPs used per one cycle of urea. And we also generate that fumar rate which is then used by the liver to potentially form glucose molecules via gluconeogenesis.
