Question

How does hemoglobin carry oxygen through the blood?​

Answer 1

Hemoglobin with bound carbon dioxide and hydrogen ions is carried in the blood back to the lungs, where it releases the hydrogen ions and carbon dioxide and rebinds oxygen. Thus, hemoglobin helps to transport hydrogen ions and carbon dioxide in addition to transporting oxygen.

Answer 2

hemoglobin bound of carbondioxide and hydrogen ions is carried in blood and taken back to the lungs where it releases hydrogen ions and catbondioxide and rebinds oxygen
