Answer 1

An increase in blood carbon dioxide content causes hemoglobin to release more oxygen molecules. Details about hemoglobin can be found below.

What is hemoglobin?

Hemoglobin is the iron-containing substance in red blood cells that transports oxygen from the lungs to the rest of the body.

Hemoglobin consists of a protein (globulin) and heme (a porphyrin ring with an atom of iron at its centre). This justifies its oxygen affinity.

However, excess carbon dioxide in the blood causes blood pH to decrease, resulting in hemoglobin proteins releasing more oxygen molecules.
