The question is referring to the hexosamine pathway.
Carbamoyl phosphate and arginine are involved in the urea cycle. So is n-acetylglutamate (NAG) (regulates production of carbamoyl phosphate).
out of curiosity, how may people knew this? (dont be shy to say you did or didnt?)
My poverty education didn't ingrain this in me.

Process of elimination on this one.
