The number of ATP equivalents that are consumed during the reactions of urea cycle. Concept introduction: The urea cycle involves the production of urea through many biochemical reactions. Five enzymes are involved in the urea cycle, namely ornithine transcarbamylase (OTC), carbamoyl-phosphate synthetase 1 (CPS1), arginase 1 (ARG1), argininosuccinate synthetase (ASS1), argininosuccinate lyase (ASL). The urea cycle involves the conversion of excess nitrogen generated from the amino acid breakdown in the proteins into an excretable form called urea.
