What is the breakdown product of heme?
The breakdown product of heme is bilirubin. Bilirubin is produced when heme is broken down in the liver as a part of the normal process of recycling heme from old red blood cells.
When red blood cells are broken down where are the heme from the hemoglobin converted to?
oxygen
Is heme broken down into iron and amino acids for the use of synthesis of new red blood cells?
Yes, heme is broken down into iron and amino acids in the process of recycling old red blood cells. The iron is reused for new red blood cell synthesis, while the amino acids are utilized for protein synthesis in the body.
When hemoglobin is recycled what happens to the heme group?
Old or damaged RBCs are removed from the circulation by macrophages in the spleen and liver, and the hemoglobin they contain is broken down into heme and globin. The globin protein may be recycled, or broken down further to its constituent amino acids, which may be recycled or metabolized. The heme contains precious iron that is conserved and reused in the synthesis of new hemoglobin molecules. During its metabolism, heme is converted to bilirubin, a yellow pigment that can discolor the skin and sclera of the eye if it accumulates in the blood, a condition known as jaundice. Instead, the plasma protein albumin binds to bilirubin and carries it to the liver, where it is secreted in bile and also contributes to the color of feces.
What is the processes through which Red Blood Cell components are recycled?
Macrophages in the spleen, liver and red bone marrow phagocytize the worn out RBCs. The heme and globin portions are split apart. The globin is broken down into its amino acid components to be used for other proteins. The iron is removed from the heme portion where it is eventually transported back to the red bone marrow to be incorporated into new RBCs. The non-iron portion of heme goes through a series of chemical conversions that eventually end up as stercobilin in the large intestine which is what gives feces its characteristic brown color.
After hemoglobin is broken down into heme and globin what ultimately happens to the heme?
Heme is decomposed into iron and biliverdin
When erythrocytes are broken down the heme group is excreted as what?
iron

When red blood cells are broken down where are the heme from the hemoglobin converted to?
oxygen
What breaks down hemoglobin in the body?
Hemoglobin in the body is broken down by an enzyme called heme oxygenase.
Will bilirubin build up in the blood if the liver is damaged?
Yes. When hemoglobin is broken down into heme and globin, the heme sends bilirubin to your liver. If your liver isn't functioning properly it won't be able to secrete it into your intestines.

Which organ breaks down red blood cell?
The spleen breaks down old red blood cells. The contained hemoglobin is released, which is further broken to globin, a protein and heme, a porphyrin.The heme is converted to bilirubin, which moves from the spleen to the liver attached to albumin. (Both feces and urine get their color from the products of the breakdown of the heme.) The iron recycled from the breakdown of the heme group is stored in the liver.

What are the products of hemoglobin breakdown?
Hemoglobin molecules liberated from red blood cells are broken down into subunits of heme, an iron containing portion, and globin, a protein. The heme further decomposes into iron and a greenish pigment called biliverdin. Biliverdin eventually is converted to an orange pigment called bilirubin.
Where from hemoglobin formed in human body?
Hemoglobin is produced in bone marrow by erythrocytes and is circulated with them until their destruction. It is then broken down in the spleen, and some of its components, such as iron, are recycled to the bone marrow. Other components, such as the heme groups, are broken down into bilirubin, transported to the liver, and secreted with the bile into the intestine for eventual elimination from the body.
