Current Question (ID: 14406)

Question:

Oxygen binding to hemoglobin in blood is:

Options:

1. directly proportional to the concentration of CO₂ in the medium.
2. inversely proportional to the concentration of CO₂ in the medium.
3. directly proportional to the concentration of CO in the medium.
4. independent of the concentration of CO in the medium.

Solution:

Oxygen binding to hemoglobin in blood is inversely proportional to the concentration of carbon dioxide (CO₂) in the medium. This is due to the Bohr effect, which is a phenomenon where an increase in the partial pressure of CO₂ or a decrease in the pH of blood causes a decrease in the binding affinity of hemoglobin for oxygen. As CO₂ concentration increases in tissues, it gets converted to carbonic acid, which dissociates into hydrogen ions and bicarbonate ions. This results in a decrease in blood pH, which causes the Bohr effect and facilitates the release of oxygen from hemoglobin to the tissues.
