COX-1 and COX-2 are free to spit it out again, but for the time that that ibuprofen is in there, the enzyme can't bind arachidonic acid, and can't do its normal chemistry.
COX-1 i 2 slobodni su ispljunuti ga van, ali za vrijeme dok je ibuprofen tamo, enzim ne može na sebe vezati arahidonsku kiselinu i ne može imati normalne reakcije.
