How much faster does CO2 bond to hemoglobin compared to O2?

The correct answer indicates that carbon dioxide (CO2) bonds to hemoglobin approximately 210 times faster than oxygen (O2). This is significant in understanding the physiological dynamics of gas exchange in the human body, particularly during episodes of asphyxiation or in conditions where CO2 levels increase, such as during certain types of fire incidents.

Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to the tissues and returns carbon dioxide from the tissues back to the lungs. Under normal conditions, the affinity of hemoglobin for oxygen is crucial for effective oxygen delivery to the body's tissues. However, CO2 can bind to hemoglobin at a much faster rate due to its chemical structure and the way it interacts with the heme group in hemoglobin.

This rapid binding of CO2 can lead to a shift in the oxygen-hemoglobin dissociation curve, which can complicate the dynamics of oxygen delivery under certain conditions, such as during smoke inhalation in firefighting scenarios. Understanding these rates helps fire investigators assess the effects of inhalation injuries and the importance of monitoring both CO2 and O2 levels in fire-related incidents.

The magnitude of the difference in binding rates is crucial in situations involving respiratory distress and highlights the importance of quick medical
