What causes the maximum uptake of oxygen while blood moves through the capillaries of the lungs?
- AEach haemoglobin molecule can temporarily bind to four oxygen atoms.
- BOxyhaemoglobin formation increases the capacity of red blood cells to transport oxygen.
- CThe binding of the first oxygen molecule to haemoglobin decreases the molecule’s affinity for binding other oxygen molecules.
- DThe dissociation of carbon dioxide from carboxyhaemoglobin allows more haemoglobin to be available for oxygen binding.
