Question 5

The oxygen-binding proteins myoglobin, fetal haemoglobin, and adult haemoglobin have different affinities for oxygen, which are reflected in their oxygen dissociation curves. The graph below shows the oxygen dissociation curves for these three proteins under physiological conditions, labeled as Curve L, Curve M, and Curve N.

Oxygen dissociation curves

Which row in the table correctly identifies Curve L, Curve M, and Curve N?

Curve L: fetal haemoglobin; Curve M: adult haemoglobin; Curve N: myoglobin

Curve L: myoglobin; Curve M: adult haemoglobin; Curve N: fetal haemoglobin

Curve L: myoglobin; Curve M: fetal haemoglobin; Curve N: adult haemoglobin

Curve L: adult haemoglobin; Curve M: fetal haemoglobin; Curve N: myoglobin
