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

亲和力增加是由血红蛋白分子的构象变化或结构变化引起的。

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.

重要的是要注意，血红蛋白的亲和力增加是由构象变化或氧结合时血红蛋白结构的变化引起的。
