Current Question (ID: 14412)

Question:

An increase from pH 7.2 to pH 7.4 around hemoglobin causes:

Options:

1. Hemoglobin to release all bound oxygen molecules.
2. An increase in the affinity of hemoglobin to bind oxygen molecules.
3. Hemoglobin to denature.
4. An increase in the binding of H+ by hemoglobin.

Solution:

This phenomenon is called the Bohr effect, where an increase in pH (decrease in H+) causes a shift of the oxygen-hemoglobin dissociation curve to the left, indicating a higher affinity of hemoglobin for oxygen. This enables hemoglobin to load more oxygen in the lungs, where the pH is higher, and unload more oxygen in the tissues, where the pH is lower due to higher levels of CO₂.
