Question

Which of the following factors are favourable for the formation of oxyhaemoglobin in alveoli ?

• A. High pO₂ and High pCO₂
• B. High pO₂ and Lesser H⁺ concentration
• C. Low pCO₂ and High H⁺ concentration
• D. Low pCO₂ and High temperature

Answer 1

The Correct Option is B

Oxyhemoglobin Formation:

• Oxyhemoglobin forms more readily when oxygen levels are high (high pO₂).
• It also forms when the concentration of H⁺ ions is lower, as in the lungs, where the pH is relatively higher.

Thus, the correct answer is (2) High pO₂ and Lesser H⁺ concentration.
