Question

About him carbon dioxide is carried by the hemoglobin as as carbon amino haemoglobin

Answer 1

carbon dioxide forms a carbonic acid amide with the amino groups at n-terminal end of each of the four submits chains that make up a hemoglobin molecule.
due to conformation changes when oxygen binds, this reaction only occur with deoxyhemoglobin, and the presence of carbon dioxide thus helps hemoglobin release bound oxygen.
however , the carbon dioxide is not directly competing with oxygen for binding to the heme iron, the way carbon monoxide does. co2 and o2 bind to completely different parts of the hemoglobin molecule.

Answer 2

Hemoglobin is contained in red blood cells, which efficiently carries oxygen from the lungs to the tissues of the body. Hemoglobin also helps in the transportation of carbon dioxide and hydrogen ions back to the lungs.
