The diagram below depicts the proportion of oxygen bound (e) by haemoglobin at different partial pressures of oxygen (pO₂) in its high-affinity state, low-affinity state and what we actually observe due to the transition made from low- to high-affinity state. Indicate whether the statements below are true or false:

in its high-affinity state haemoglobin would be fully saturated by oxygen in
tissue.
due to the transition between states, haemoglobin is able to fully release
oxygen in the lungs.
in its high-affinity state haemoglobin would release oxygen in tissues.
in its low-affinity state haemoglobin would be fully saturated by oxygen in
lungs.
