What is the role of hemoglobin's quaternary structure in facilitating oxygen transport?
A
It allows for the binding of oxygen to the heme group
B
It enables the transport of carbon dioxide from tissues to lungs
C
It facilitates the cooperative binding of oxygen to the four subunits
✓
D
It regulates the pH of the blood
Explanation
The quaternary structure of hemoglobin allows for cooperative binding of oxygen, where the binding of oxygen to one subunit increases the affinity for oxygen in the other subunits.
