Question 1 of 5
What factor affects the binding of carbon dioxide (CO₂) to hemoglobin?
Correct Answer: B
Rationale: The binding of carbon dioxide (CO₂) to hemoglobin is primarily influenced by the partial pressure of carbon dioxide (pCO₂) in the blood. When pCO₂ is high, such as in the tissues, more binding of CO₂ to hemoglobin occurs. Conversely, when pCO₂ is low, as in the alveoli, dissociation of CO₂ from carbamino-hemoglobin takes place.
