WebSo hemoglobin is allosterically inhibited by carbon dioxide and by protons. So carbon dioxide can bond to other parts of the hemoglobin-- I don't know the exact spots-- and so can protons. So remember, acidity just means a high concentration of protons. So if you're in an acidic environment, protons can bond. talbot county georgia government
