WebApr 1, 2024 · The Bohr Effect is the influence of pH on the oxygen affinity of haemoglobin molecules in the blood. Carbon dioxide can be carried in the blood, but only if oxygen and haemoglobin are present in a free form. The Haldane effect occurs when oxyhaemoglobin levels are low and carbon dioxide levels are high in the blood. WebFigure 1.
