Which of the following is true regarding effectors of oxygen-hemoglobin binding? A) actively metabolizing tissues produce acid which increases hemoglobin's affinity for oxygen B) the presence of CO₂ enhances the release of oxygen from hemoglobin C) 2,3-bisphosphoglycerate must dissociate from hemoglobin before oxygen can be released D) the presence of protons will counter the effect of CO₂ on the realease of oxygen by hemoglobin E) none of the above
