Carbon dioxide carry in blood occurs mainly in 3 forms: liquified (about 5%); as the bicarbonate anion (about 90%); and also as carbamino compound (about 5%).

You are watching: Most carbon dioxide is transported in the blood as

Bicarbonate

Bicarbonate is produced by the reaction of carbon dioxide with water to kind carbonic acid, i beg your pardon dissociates into hydrogen and also bicarbonate. The reaction the carbon dioxide and water in red blood cell is catalytic analysis by carbonic anhydrase.

Figure 1. Most of carbon dioxide is transported in the blood together bicarbonate anions, i m sorry are developed from the catalysis of carbon dioxide and water by carbonic anhydrase to kind carbonic acid.

Carbamino compounds

Carbamino compound are formed via the reaction of carbon dioxide through the terminal amino groups of blood proteins, consisting of hemoglobin.

Figure 3. The carbon dioxide-hemoglobin dissociation curve defines the Haldane effect. The amount of carbon dioxide (CO2) in the blood at any type of given level of carbon dioxide stress (PCO2) is dependency on the quantity of hemoglobin oxygenation. More oxygen unloaded right into the peripheral tissues means that the hemoglobin will certainly bind much more avidly to CO2.
