What is a possible outcome to the urea cycle if the cell is unable to produce enough aspartate?

Question

Quizplus · Accepted Answer

Aspartate is required as a substrate for the synthesis of argininosuccinate during the urea cycle. Therefore, if the cell is unable to produce enough aspartate, the conversion of citrulline to argininosuccinate would be limited, resulting in the buildup of citrulline in the cycle. This option is the only one that correctly describes the outcome of a lack of aspartate in the urea cycle.
