Acid

Vedclass · Answer

(B) Oxyhemoglobin $(HbO_2)$ is a stronger acid than deoxyhemoglobin $(Hb)$.When oxygen binds to hemoglobin in the lungs,it promotes the release of hydrogen ions $(H^+)$ from the hemoglobin molecule.Because it is a stronger acid,it dissociates more readily,releasing $H^+$ ions into the blood,which helps in the transport of carbon dioxide via the chloride shift mechanism.Therefore,oxyhemoglobin functions as an acid in the physiological system.
