<prompt> In urea cycle, hydrolysis occurs during:Cleavage of ArginineCleavage of ornithineFormation of ArgininosuccinateFormation of citrulline  <response>: Arginase the final enzyme of urea cycle is a hydrolase i.e. it uses water to break the bond in arginine It breaks arginine into urea and ornithine Urea is transpoed to kidneys from liver blood and then excreted in urine
