As carbon dioxide enters systemic blood,it causes more oxygen to dissociate from hemoglobin (the Haldane effect),which in turn allows more CO₂ to combine with hemoglobin and more bicarbonate ions to be generated (the Bohr effect).

Question

The statement confuses the Haldane and Bohr effects. The Bohr effect describes how increased CO2 levels and decreased pH lead to more oxygen dissociating from hemoglobin, while the Haldane effect explains how deoxygenation of blood increases its ability to carry CO2.
