The protein buffer system is part of the body's mechanism for controlling blood Hydrogen (H+) ion homeostasis. Both intracellular and extracellular proteins have negative charges and can serve as buffers for alterations in hydrogen ion concentration. However, because most proteins are inside cells, this primarily is an intracellular buffer system. Haemoglobin (Hb) is an excellent intracellular buffer because of it's ability to bind with Hydrogen ions forming a weak acid and carbon dioxide (CO2). After oxygen is released in the peripheral tissues, haemoglobin binds with CO2 and H+ ions. As the blood reaches the lungs these actions reverse themselves. Haemoglobin binds with oxygen, releasing the CO2 and H+ ions. The H+ ions combine with bicarbonate (HCO3) ionsto form carbonic acid (H2CO3). The H2CO3 breaks down to form water (H2O) and carbon dioxide (CO2) which are excreted via expiration through the lungs. Therefore respirations help maintain pH.

In lysis buffer urea denature the protein and increase the solubility of protein.
How does the Blood buffer system work?
Buffer systems help to maintain constant plasma pH. There are three buffer systems: Protein buffer system, phosphate buffer system and bicarbonate buffer system. Among these, the bicarbonate buffer system is the most predominant. Buffer Systems function as "shock absorbers" that accept excess H+ ions or OH- ions and keep blood pH constant. For example, if there is an increase in acidity of blood due to excess HCl (a strong acid), then NaHCO3 (Sodium bicarbonate) will buffer it to a weak acid (H2CO3). HCl+NaHCO3 = NaCl+H2CO3
What is the major buffer system in human blood?
Buffer systems help to maintain constant plasma pH. There are three buffer systems - Protein buffer system, phoshate buffer system and bicarbonate buffer system.

How did binding buffer get its name?
A binding buffer is a substance used in chromatography to fix a specific compound.For example this buffer can be linked to a protein.
What are some examples of an organic buffer?
blood,protein

What two organs are most important to physical buffer systems?
buffer systems function mainly to regulate the acid or base balance in the body. there are 3 principal classes of buffers in the body - proteins, phosphate buffer system and the bicarbonate buffer system. however, you are asking of the organs involved. these are the kidneys and the lungs.
