Which of the following regarding the effect of protons on binding of O₂ by hemoglobin is NOT correct?
A)The saturation curve of Hb for O₂ is displaced to the left (greater binding)as acidity increases.
B)Actively metabolizing tissues produce acid,which is an antagonist of oxygen binding by Hb.
C)As pH decreases,dissociation of O₂ from Hb is enhanced.
D)The phenomenon is called the Bohr effect.

Question

The saturation curve of Hb for O₂ is actually displaced to the right (lesser binding) as acidity increases, not to the left. This reflects decreased affinity of hemoglobin for O₂ at lower pH levels.
