Uplоаd аn imаge оf yоur drawings. Show the steps in the urea cycle that result in the formation of Arg from citrulline. Include substrate and product structures and any necessary cofactors, and circle the N atom in the structure of Arg that becomes one of the N atoms in ornithine. (5 points) The urea cycle is intertwined with the citric acid cycle. Diagram how these cycles are connected (i.e. what structures are common to both cycles) and indicate how a citric acid cycle compound becomes a N atom donor for urea production. Just show the reactions, names or structures of compounds are fine. (4 points) The final reaction that forms urea in the urea cycle is catalyzed by the enzyme arginase. Beginning with this reaction, show how the amino acid Arg is converted to the 5-carbon compound found in the citric acid cycle via an amino transferase catalyzed formation of an aldehyde intermediate. Show the structures involved along with required cofactors and give the reaction type for each step (enzyme names are not required), i.e. carboxylation hydration, oxidation, etc. (4 points)
