Catabolism of haemoglobin produces ________ and ________ .
- Aurochrome, urea
- Bbilirubin, uric acid
- Correct answerCamino acids, bilirubin
- Durochrome, bilirubin
Solution
Haemoglobin is a conjugated protein consisting of a protein part called globin and a non-protein part called haem.
During the catabolism of haemoglobin, the globin portion is broken down into its constituent amino acids, which can be reused by the body.
The haem portion is degraded to release iron and a porphyrin ring. The porphyrin ring is further converted into biliverdin, which is subsequently reduced to bilirubin.
Therefore, the catabolism of haemoglobin produces amino acids and bilirubin.
Answer: amino acids, bilirubin
