1. carbon dioxide released during respiration can affect the % oxygen saturation of haemoglobin. Carbon dioxide reacts with water to form carbonic acid. Which statements below explains the effect of carbon dioxide on haemoglobin? A. The release of hydrogen ions causes the pH to rise, which reduces haemoglobin's affinity for oxygen. B. The release of hydrogen ions causes the pH to rise, which increases haemoglobin's affinity for oxygen. C. The release of hydrogen ions causes the pH to fall, which increases haemoglobin's affinity for oxygen. D. The release of hydrogen ions causes the pH to fall, which reduces haemoglobin's affinity for oxygen. E. None of the above can explain the change. 2.
