Explanation:
Detailed explanation-1: -In peripheral tissues, where oxygen content is low, carbon dioxide binds to hemoglobin to form carbaminohemoglobin.
Detailed explanation-2: -When carbon dioxide diffuses as a dissolved gas from the tissue capillaries, it binds to the -amino terminus of the globulin chain, forming Carbaminohemoglobin.
Detailed explanation-3: -When carbon dioxide binds to hemoglobin, a molecule called carbaminohemoglobin is formed. Binding of carbon dioxide to hemoglobin is reversible. Therefore, when it reaches the lungs, the carbon dioxide can freely dissociate from the hemoglobin and be expelled from the body.
