Percentage of bilirubin production from old RBCs: (A) 20%, (B) 80%, (C) 100%, (D) 40%
Answer is B. (B) 80% > Bilirubin is the end product of heme degradation.> From 70 to 90% of bilirubin is derived from degradation of the hemoglobin of senescent red blood cells.> Bilirubin produced in the periphery is transported to the liver within the plasma, where, due to its insolubility in aqueous solutions, it is tightly bound to albumin.
