Increased affinity is caused by a conformational change, or a structural change in the hemoglobin molecule.

It is important to note that the increased affinity of hemoglobin results from a conformational change, or a change in the structure of hemoglobin when the oxygen binds.
In biochemistry, a conformational change is a change in the shape of a macromolecule, often induced by environmental factors.
A macromolecule is usually flexible and dynamic. It can change its shape in response to changes in its environment or other factors; each possible shape is called a conformation, and a transition between them is called a conformational change. Factors that may induce such changes include:
