amino acids on hemoglobin are responsible for carrying carbon dioxide from Rosie's to lungs

Step 1
Hemoglobin is a protein found in red blood cells that primarily carries oxygen from the lungs to the tissues and helps transport carbon dioxide from the tissues back to the lungs. Show more…

In addition to transporting oxygen, hemoglobin also helps maintain a constant blood pH of around 7.4. The binding of oxygen to hemoglobin causes a conformational change that disrupts salt bridges, lowering the pKa of the basic amino acids that form the salt bridge. Consequently, hemoglobin acts as a simple buffer in which oxyhemoglobin (HbO2) has a pKa of about 6.7 and deoxyhemoglobin (Hb) has a pKa of about 7.8. HHbO2 <=> H+ + HbO2
