Carbamoyl-Phosphate Synthetase I is an enzyme located within the Mitochondria during the Urea Cycle; with its production, Urea will subsequently be formed. Urea will then be transported throughout the blood back to the kidneys where excretion will ensue. It is comprised from a series of reaction, The set of reactions begins with the phosphorylation of bicarbonate. This bicarbonate molecule will then bind an ammonia from glutamine thereby causing a reaction with carboxyphosphate. This will result in the production of Carbomate which is then phosphorylated to become carbamoyl-phosphate.
