How does the oxyen binding kinetics/mechanism of hemoglobin facilitate its function in lungs and in other tissues (like muscles)?
Added by Marilyn W.
Step 1
The quaternary structure allows for cooperative binding, meaning the binding of oxygen to one subunit increases the affinity of the remaining subunits for oxygen. Show more…

If hemoglobin has such a high affinity for oxygen, how is it able to release oxygen for use by tissue? How does exercise specifically affect the release of oxygen from hemoglobin? How is this process reversed at the lungs?

How do you suppose that a molecule of hemoglobin is able to bind oxygen efficiently in the lungs, and yet release it efficiently in the tissues?
Sri K.
Hemoglobin functions as an oxygen carrier by....: Binding O2 via its heme group with varying strength due to cellular environment and allosteric interactions Binding an O2 molecule due to the pKa of Lysine residues Clamping O2 molecules between His residues on neighboring subunits Oxidizing the Fe2+ ion on the heme in the lungs and then oxidizing H2O back to O2 in the muscles.
