What is the advantage to the organism of the difference between the curve?

(a) Haemoglobin removes more $CO_2$ from active tissues

(b) Haemoglobin can release oxygen to myoglobin

(c) $CO_2$ is readily released into the alveoli

(d) Oxygen is readily released into active tissues

Answer: (d)

Actively respiring tissues require more oxygen. They are also associated with high partial pressures of carbon dioxide since it is a product of respiration. The curves show that oxygen would be more readily released at higher partial pressures of carbon dioxide, i.e. at active tissues.
