What is true of urea biosynthesis?

Urea cycle takes place in the liver. The urea is synthesized from ammonia and carbon dioxide. It is a 5 step cyclic process, with five distinctive enzymes. The first two steps of the urea cycle take place in mitochondria and next three in the cytosol. As the first two steps of the urea cycle take place in mitochondria there respective urea cycle enzymes are located inside mitochondria. So, the correct answer is 'Urea cycle enzymes are located inside mitochondria'.
