Final answer:
Bilirubin is the breakdown product of hemoglobin. It is a yellow pigment that gives color to urine and feces.
Step-by-step explanation:
The breakdown product of hemoglobin is bilirubin.
Hemoglobin is broken down in the liver, and the non-iron portion of heme is degraded into biliverdin, a green pigment. Biliverdin is then converted into bilirubin, a yellow pigment. Bilirubin is used by the liver to manufacture bile, which is eventually eliminated from the body in the feces. It is important in giving color to urine and feces.
