Question

A low level of oxyhaemoglobin enables the blood to transport more CO2, this phenomenon is known as:

• A. Bohr effect
• B. Haldane effect
• C. Chloride shift
• D. Alkalosis

Answer 1

Answer:

B. Haldane effect

The Haldane effect is a physicochemical phenomenon that occurs when hemoglobin has a lower oxygen saturation. In this state, hemoglobin has a higher affinity for CO2 and can bind more of it. When the blood becomes oxygenated in the lungs, the CO2 dissociates from the hemoglobin and is removed from the body.
