Question: What acute metabolic condition can be defined by the elevation of a yellow compound that occurs in normal catabolic pathway that breaks down heme in vertebrates? 
Sentence (from "Bilirubin"): This catabolism is a necessary process in the body's clearance of waste products that arise from the destruction of aged red blood cells. First the hemoglobin gets stripped of the heme molecule which thereafter passes through various processes of porphyrin catabolism, depending on the part of the body in which the breakdown occurs.
Relevant evidence: No
