Can hemoglobin bind co2

Hemoglobin can bind protons and carbon dioxide, which causes a conformational change in the protein and facilitates the release of oxygen. Protons bind at various places on the protein, while carbon dioxide binds at the α-amino group. Carbon dioxide binds to hemoglobin and forms carbaminohemoglobin.

WebMar 10, 2024 · The Function of Hemoglobin. Hemoglobin binds and transports oxygen from the lungs to the tissues in the body. It also transports carbon dioxide from tissues … WebDrawn by J. Shaw at BYU-Idaho, Winter 2014. In the tissues, carbon dioxide levels elevate, so it diffuses into blood and enters the red blood cells to be converted to carbonic acid by the enzyme carbonic anhydrase. Hydrogen ions are released and bind to hemoglobin causing more oxygen to be released to the tissues (Bohr effect).
