Scientists have shown that the oxygen dissociation curves for haemoglobin of smaller mammals are to the right of those of larger mammals.
What does this suggest about the haemoglobin of smaller mammals?
1 )
At low partial pressures of oxygen, it binds to oxygen more strongly than the haemoglobin of larger mammals.
2 )
It saturates with oxygen at lower partial pressures of oxygen than the haemoglobin of larger mammals.
It releases oxygen more easily than the haemoglobin of larger mammals.
4 )
When the partial pressure of oxygen is high, it carries more oxygen than the haemoglobin of larger mammals.
