Urea Cycle Flashcards
excess protein more commonly stored as fat. what is other thing our body does with it
converts to glucose to make ATP
losing nitrogen is the process of
deamination
nitrogen is unique to
protein
if we don’t excrete nitrogen it converts into
ammonia
why is ammonia poisonous
highly basic
hydrogen ions are what subatomic particles
protons
what effect would ammonia have on inter-membrane space
as in ETC it’s acidic with H+ ions in would neutralise pH - ATP synthase wouldn’t work properly
ammonia written as
NH3
where does urea cycle occur
liver
kidneys if nec
in urea cycle free CO2 and NH3 make
carbamoyl phosphate
which enzyme turns CO2 & NH3 into carbamoyl phosphate
carbamoyl phosphate synthase
carbamoyl phosphate combines with what to make what
ornithine to make citruline
Citruline combines with what to make what
aspartate to make arginosuccinate
arginosuccinate then makes what (2)
L-Arginine
Fumerate - off to krebs
Arginine then makes (2)
Urea
Ornithine
