Heme Catabolism and Degradation Pathway - Biochemistry Lesson

The video explains heme catabolism, starting with the breakdown of red blood cells and hemoglobin. It details the role of the reticuloendothelial system in processing hemoglobin and the conversion of heme to biliverdin and then to bilirubin. The transport and conjugation of bilirubin in the liver are discussed, followed by its excretion through feces and urine. The video concludes with a summary of the process and some quick facts about red blood cells and bilirubin levels.

How is bilirubin transported in the bloodstream?

What happens to bilirubin in the liver?

Describe the process of urobilinogen conversion in the intestines.

What are the normal serum levels of bilirubin in adults?
