Buffer Systems of Blood Biochemistry - Biology Discussion

WebProtein buffer systems depend upon proteins, as opposed to nonprotein molecules, to act as buffers and consume small amounts of acid or base. The protein hemoglobin makes an excellent buffer. It can bind to small amounts of acid in the blood, helping to remove that acid before it changes the blood's pH. Many other proteins act as buffers as well. Web10 mrt. 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 back to the lungs. 2.
