In the case of respiratory distress where CO2 levels rise, what happens to the binding of oxygen to hemoglobin?

How is hemoglobin binding of oxygen affected by CO2? Increase Decrease No change
Adi S.
Carbon dioxide released during respiration can affect the % oxygen saturation of hemoglobin. Carbon dioxide reacts with water to form carbonic acid. Which statement below explains the effect of carbon dioxide on hemoglobin? A. The release of hydrogen ions causes the pH to rise, which reduces hemoglobin's affinity for oxygen. B. The release of hydrogen ions causes the pH to rise, which increases hemoglobin's affinity for oxygen. C. The release of hydrogen ions causes the pH to fall, which increases hemoglobin's affinity for oxygen. D. The release of hydrogen ions causes the pH to fall, which reduces hemoglobin's affinity for oxygen. E. None of the above can explain the change. 2. The following events occur when carbon dioxide enters an erythrocyte in a capillary. 1. Hydrogen carbonate ions diffuse into the plasma from the red blood cells. 2. Dissociation of carbonic acid 3. Carbon dioxide reacts with water, forming carbonic acid 4. Chloride ions diffuse into red blood cells from plasma First step to Final step: A. 2 4 1 3 B. 3 2 1 4 C. 3 1 4 2 D. 2 3 4 1 E. 2 3 1 4 3. Fetal hemoglobin is able to obtain oxygen from maternal blood because A. Fetal blood is more acidic than maternal blood. B. Maternal blood is more acidic than fetal blood. C. Fetal red blood cells contain more hemoglobin than maternal red blood cells do. D. Maternal hemoglobin binds BPG weaker. E. Fetal hemoglobin binds BPG weaker.
