What is the role of hemoglobin's alpha-globin chains in maintaining the stability of the hemoglobin molecule?
A
To facilitate the binding of oxygen to the heme group
B
To regulate the release of oxygen to the tissues
C
To provide a site for the attachment of 2,3-Bisphosphoglycerate
D
To maintain the tetrameric structure of the hemoglobin molecule
✓
Explanation
The alpha-globin chains play a crucial role in maintaining the stability of the hemoglobin molecule by forming a tetrameric structure with the beta-globin chains.
