What is the primary function of the hemoglobin subunit alpha-globin in the context of hemoglobin and oxygen transport?

A To bind to oxygen and facilitate its transport to tissues
B To regulate the production of red blood cells
C To maintain the structural integrity of the hemoglobin molecule
D To catalyze the conversion of methemoglobin to normal hemoglobin
The alpha-globin subunit plays a crucial role in binding to oxygen and facilitating its transport to tissues, making it essential for oxygen delivery.
