Did you know?
WebHowever, hemoglobin also contains a porphyrin called heme that cannot be recycled and must be eliminated. Elimination of heme is accomplished in a series of steps: Within the phagocytic cells, heme is converted through a series of steps into free bilirubin, which is released into plasma where it is carried around bound to albumin, itself a ... WebHemoglobin can be recycled only if phagocytized by macrophages. b. Each heme is stripped of its iron and converted to bilirubin, then excreted in bile. c. The alpha and beta …
WebAbout 95 percent of the dry weight of the red blood cell consists of hemoglobin, the substance necessary for oxygen transport.Hemoglobin is a protein; a molecule contains four polypeptide chains (a tetramer), each chain consisting of more than 140 amino acids. To each chain is attached a chemical structure known as a heme group. Heme is … WebHemoglobin is produced in bone marrow by erythrocytes and is circulated with them until their destruction.
