What is the maximum amount of oxygen that can be carried by each haemoglobin molecule?
What is the maximum amount of oxygen that can be carried by each haemoglobin molecule?
1 molecule of oxygen
2 molecules of oxygen
3 molecules of oxygen
4 molecules of oxygen
Solution
Each haemoglobin molecule can carry a maximum of four molecules of oxygen, when conditions are favorable for the formation of oxyhaemoglobin, such as high pO₂, low pCO₂, lesser H⁺ concentration, and lower temperature.
