Question

Effect of $C{O}_2$ concentration on dissociation of oxyhaemoglobin is called

• A. Bohr's effect
• B. Haldane effect
• C. Hamburger effect
• D. Gaudikov's effect

Answer 1

The correct option is A Bohr's effect

The amount of carbon dioxide increases, more $H^{+}$ are formed and the pH will decrease. Thus, a lower pH in the blood indicates an increased carbon dioxide concentration, which in turn is suggestive of a more active tissue, that requires more oxygen. According to Bohr, the lower pH will cause Hb to deliver more oxygen.
