Current Question (ID: 14358)

Question:

Why the partial pressure of CO₂ is high at tissue-site?

Options:

1. Due to the saturation of O₂ with Hb
2. Release of H⁺ at the tissue site
3. Due to metabolism
4. Due to the dissociation of HbO₂

Solution:

CO₂ is produced as a byproduct of metabolism in the tissues. As a result, the partial pressure of CO₂ is high at the tissue site. The CO₂ then diffuses from the tissue cells into the blood, where it combines with water to form carbonic acid. This reaction is catalyzed by carbonic anhydrase, which is present in the red blood cells. The carbonic acid then dissociates into bicarbonate ions and hydrogen ions. The hydrogen ions are buffered by hemoglobin, which can bind to them and prevent a decrease in blood pH. The bicarbonate ions are transported back to the lungs, where they are converted back into CO₂ and water, which are then exhaled.
