Hemoglobin, a complex protein in red blood cells, carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. It consists of four polypeptide chains and can bind up to four oxygen molecules. Myoglobin, on the other hand, is a single...
The meaning of HEMOGLOBIN is an iron-containing respiratory pigment of vertebrate red blood cells that consists of a globin composed of four subunits each of which is linked to a heme molecule, that functions in oxygen transport to the tissues after conv
in the placenta, where the pO2is lower than it is in the lungs. The higher affinity (lowerP50) of fetal hemoglobin is due to its lower affinity for BPG. Because BPG binding and O2binding interfere with each other, reduced affinity for the former means increased affinity for the latter. ...
Hemoglobin is a protein molecule found in red blood cells (erythrocytes) that carries oxygen from the lungs to the rest of the body. Without hemoglobin, your red blood cells cannot deliver the oxygen that your cells need to produce energy. Hemoglobin is vital for human life. Hemoglobin is a...
Hemoglobin (abbreviated Hgb or Hb) is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. Hgb is made up of four protein molecules (globulin chains) that are connected. The normal ...
The protein in the red blood cells of vertebrates that carries oxygen from the lungs to tissues and that consists of four polypeptide subunits, each of which is bound to an iron-containing heme molecule. [Ultimately short forhematinoglobulin:hematin+globulin.] ...
There are several molecules, ions, and conditions that promote the timely binding of oxygen to hemoglobin in the lungs and release in the tissues and cells. These are hydrogen ion (H+ and pH), pCO2, temperature, and 2,3-DPG. Conditions of higher metabolic demand or oxygen consumption, as...
releases carboxyhemoglobin in the lungs (which is exhaled) and picks up more oxygen to bring to the cells. When people inhale exhaust fumes from gasoline engines, the chemicals from the fumes displace oxygen from oxyhemoglobin and cause the formation and buildup of carboxyhemoglobin. The buildup...
