Carbon dioxide occupies a different binding site on the hemoglobin. Carbon dioxide is more readily dissolved in deoxygenated blood, facilitating its removal from the body after the oxygen has been released to tissues undergoing metabolism. This increased affinity for carbon dioxide by the venous blood...

The respiratory protein of the red blood cells, it transfers oxygen from the lungs to the tissues and carbon dioxide from the tissues to the lungs. Its affinity for carbon monoxide is >200 times that for oxygen. Hemoglobin is a conjugated protein of molec ...
The concept of the Haldane effect, like that of the Bohr effect in oxygen carriage, is that the affinity of hemoglobin for carbon dioxide varies with chemical conditions such as Po2. When hemoglobin is oxygenated in the lung to release hydrogen ions, carbonic acid and ultimately carbon dioxide...
Hemoglobin serves as a carrier of oxygen in blood and plays a role in the transport of carbon dioxide and hydrogen ion, thereby participating on the acid-base equillibrium maintanance. The affinity of carbon monoxide for a hemoglobin molecule is 250 times greater than that of oxygen, which ...
An iron-containing protein in the blood of many animals that, in vertebrates, carries oxygen from the lungs to the tissues of the body and carries carbon dioxide from the tissues to the lungs. Hemoglobin is contained in the red blood cells of vertebrates and gives these cells their characteris...
Confirming the work of other investigators, hemolysis was shown to diminish the influence exerted by carbon dioxide upon the affinity of oxygen for hemoglobin (Bohr effect). There was no consistent difference between blood taken from salmon acclimated to summer and winter conditions. Furthermore, ...
It is also shown that approximately 35% of the change in hemoglobin oxygen affinity resulting from an alteration in red cell 2,3-DPG, is explained by effect of 2,3-DPG on the red cell pH. 展开 关键词: Arteries Blood Acidosis Alkalosis Carbon Dioxide ...
Carbon dioxide can affect the affinity of hemoglobin for oxygen because: 1) it changes the partial pressure of oxygen. 2) increase the kinetic energy of the hemoglobin. 3) alters pH of the blood. 4) reduces the solubility of oxygen in the blood. ...
Evaluation of the Cd/hemoglobin affinity assay for the rapid determination of metallothionein in biological tissues. A modification of the Cd/hemoglobin affinity assay described by S. Onosaka, T. Keiichi, M. Doi, and O. Kunio (1978, Eisei Kagaku 24, 128鈥 131) was evaluate... DL Eaton,BF...
