The Bohr effect and the Haldane effect describe how hemoglobin alters its affinity for oxygen and carbon dioxide based on environmental acidity, gas concentrations, and metabolic demands. In active tissues, elevated carbon dioxide and hydrogen ions stabilize the deoxygenated T-state of hemoglobin, prompting the release of oxygen to fuel cellular respiration. Simultaneously, the chloride shift exchanges bicarbonate and chloride ions across the red blood cell membrane to maintain electrical neutrality and regulate blood pH. Conversely, when blood reaches the lungs, high oxygen levels reverse these processes to facilitate the elimination of carbon dioxide through exhalation. Together, these interrelated physiological mechanisms optimize gas exchange and ensure efficient respiratory transport throughout the body.
