Hemoglobin Hemoglobin is the iron-containing protein found in all red blood cells (RBCs) that gives the cells their characteristic red color. Hemoglobin enables RBCs to bind to oxygen in the lungs and carry it to tissues and organs throughout the body. It also helps transport a small portion of carbon dioxide, a product of cell metabolism, from tissues and organs to the lungs, where it is exhaled.

Structural Biochemistry/Protein function/Heme group/Myoglobin Myoglobin, an iron-containing protein in muscle, receives oxygen from the red blood cells and transports it to the mitochondria of muscle cells, where the oxygen is used in cellular respiration to produce energy.

Hemoglobin Oxygen binds reversibly to these iron atoms and is transported through blood. Each of the protein chains is similar in structure to myoglobin, the protein used to store oxygen in muscles and other tissues. However, the four chains of hemoglobin give it some extra advantages, as described below.

Iron Iron Iron is a trace mineral needed to make hemoglobin, the protein needed to carry oxygen throughout the body. Hemoglobin gives red blood cells their color, and stores most of the body s iron supply. Iron is also stored in muscle tissue, and helps supply the muscles with the oxygen needed to make them contract.

Human Physiology/Print Version Iron is normally absorbed from food and transported throughout the body by binding to transferrin, a protein produced by the liver. About 70% of the iron transported is incorporated into the production of red blood cell hemoglobin. The remainder is stored in the tissues as ferritin or hemosiderin, with additional small amounts used to produce other proteins such as myoglobin and some enzymes.

Role of Iron in the Body Iron is required for the production of red blood cells (a process known as haematopoiesis), but it's also part of haemoglobin (that is the pigment of the red blood cells) binding to the oxygen and thus facilitating its transport from the lungs via the arteries to all cells throughout the body.

4. Transport of Blood Gases and Metabolism of Hemoglobin Hemoglobin (Hb), the pigment that gives blood its red colour, provides the transport of blood gases. It carries oxygen from lungs to the rest of the body and a portion of carbon dioxide in the opposite direction. Hb transports 98 % of the total oxygen present in the blood and 23 % of CO2. Hemoglobin also forms an important blood buffer system, which removes the excess of H+ (particularly in peripheral tissues) by binding them to the His- residues of its molecule.

Iron Iron helps red blood cells deliver oxygen from the lungs to cells all over the body. Once the oxygen is delivered, iron then helps red blood cells carry carbon dioxide waste back to the lungs to be exhaled. Iron also plays a role in many important chemical reactions in the body.

Transport of Gases Gas Transport by the Blood. Almost all the oxygen (over 98%) is carried in the blood by attachment to hemoglobin, a protein in the red blood cells. As oxygen is dissolved in the blood, it rapidly combines with the hemoglobin to form oxyhemoglobin.Each hemoglobin molecule can bind up to four oxygen molecules.as Transport by the Blood.

- Answered by The Community. Making the world better, one answer at a time. The red blood cell is the iron-containing compound that carries oxygen in the bloodstream. The color of red blood cells will even change due to the concentration of iron in the blood.olar bears get oxygen into their bloodstream in essentially the  same way that humans, and all mammals, birds and reptiles, do. When  polar bears breathe, their lungs fill … with a mixture of gases  including oxygen.

- Hemoglobin is a metalloprotein, containing iron, that is within red blood cells and binds to gasses like oxygen in order to transport those gasses in the blood.xygen molecules are bound to the red pigment HEMOGLOBIN, a protein complex found exclusively in red blood cells. A very small amount of oxygen is also dissolved in the liquid … portion of blood, but hemoglobin carries the bulk of oxygen.

Red Blood Cells Red blood cells contain a protein called hemoglobin that gives blood its red hue. Hemoglobin contains iron, which makes it an excellent vehicle for transporting oxygen and carbon dioxide. As blood passes through the lungs, oxygen molecules attach to the hemoglobin. When the blood passes through the body’s tissue, the hemoglobin releases oxygen to the cells. The empty hemoglobin molecules then bond with the tissue’s carbon dioxide or other waste gasses to transport them away.

Key Concepts: In the body, the iron in the heme is coordinated to the four nitrogen atoms of a porphyrin and also to a nitrogen atom of a histidine amino-acid residue in the hemoglobin protein (Figure 4). The sixth position (coordination site) around the iron of the heme is occupied by O 2 when the hemoglobin protein is oxygenated.

Transport of oxygen in the blood Red blood cells and haemoglobin. Oxygen is one of the substances transported with the assistance of red blood cells. The red blood cells contain a pigment called haemoglobin, each molecule of which binds four oxygen molecules.Oxyhaemoglobin forms.he curve shows that: 1  at relatively low oxygen concentrations there is uncombined haemoglobin in the blood and little or no oxyhaemoglobin, e.g. in body tissue. 2  at relatively high oxygen concentrations there is little or no uncombined haemoglobin in the blood; it is in the form of oxyhaemoglobin, e.g. in the lungs.
