In tissue, cellular respiration produces carbon dioxide as a waste product; as one of the primary roles of the cardiovascular system, most of this CO 2 is rapidly removed from the tissues by its hydration to bicarbonate ion. [6] The bicarbonate ion present in the blood plasma is transported to the lungs, where it is dehydrated back into CO 2 ...
Carbon dioxide (CO 2) is produced in tissues as a byproduct of normal aerobic metabolism. It dissolves in the solution of blood plasma and into red blood cells (RBC), where carbonic anhydrase catalyzes its hydration to carbonic acid (H 2 CO 3). Carbonic acid then spontaneously dissociates to form bicarbonate Ions (HCO 3 −) and a hydrogen ion ...
The bicarbonate ion (hydrogencarbonate ion) is an anion with the empirical formula HCO − 3 and a molecular mass of 61.01 daltons; it consists of one central carbon atom surrounded by three oxygen atoms in a trigonal planar arrangement, with a hydrogen atom attached to one of the oxygens.
In respiratory acidosis, the kidney produces and excretes ammonium (NH 4 +) and monophosphate, generating bicarbonate in the process while clearing acid. There is also an excretion of Cl- and a reabsorption of sodium, resulting in a negative urinary anion gap. [5] In respiratory alkalosis, less bicarbonate (HCO 3 −) is reabsorbed, thus ...

The opposite is true where a decrease in the concentration of carbon dioxide raises the blood pH which raises the rate of oxygen-hemoglobin binding. Relating the Bohr effect to carbonic anhydrase is simple: carbonic anhydrase speeds up the reaction of carbon dioxide reacting with water to produce hydrogen ions (protons) and bicarbonate ions.
The parietal cell releases bicarbonate into the bloodstream in the process, which causes a temporary rise of pH in the blood, known as an alkaline tide. The gastric juice also contains digestive enzymes produced by other cells in the gastric glands – gastric chief cells. Gastric chief cells secrete an inactivated pepsinogen.
It is essential for maintaining the balance of gases in the bloodstream and to guarantee the removal of waste carbon dioxide from the body. [17] Buffering Blood pH: The binding of carbon dioxide to hemoglobin helps buffer blood pH. When tissues produce carbon dioxide, the increase in acidity is reduced by forming bicarbonate ions.
