Question

What is the chemical equation for the reversible binding of oxygen to hemoglobin?
Options
A Hb + CO₂ ⇌ HbCO₂
B Hb + 4O₂ ⇌ HbO₈
Correct Answer
C Hb + O₂ ⇌ HbO
D HbO₈ ⇌ Hb + 4O
Correct Answer

Option B is the correct answer.

Detailed Explanation

Oxygen binds reversibly to hemoglobin: Hb + 4O₂ ⇌ HbO₈, allowing oxygen to be loaded in the lungs and unloaded in the tissues.
