Question

The protein myoglobin binds a small molecule ligand called

molecular oxygen (O2) with a 1:1 molar ratio. Half of the binding sites of myoglobin are

occupied when the oxygen tension, also known as the partial pressure (or pO2), is 2.8 torr.

At what oxygen concentration (expressed in pO2) will myoglobin 70% saturated with

oxygen?
