Concept explainers
(a)
Interpretation: To identify whether carbon monoxide is encountered in the (1) urea cycle, (2) heme degradation process, or (3) oxidative deamination reaction.
Concept introduction: A urea cycle is a cyclic biochemical pathway that involves the production of urea using ammonium ions and aspartate molecules as nitrogen sources. The desired product of the urea cycle is urea.
Heme potion of hemoglobin undergoes a stepwise degradation to biliverdin, to bilirubin, and then to bile pigments that are excreted from the body.

(b)
Interpretation: To identify whether stercobilin is encountered in the (1) urea cycle, (2) heme degradation process, or (3) oxidative deamination reaction.
