The bulk of carbon dioxide is carried chemically combined with the amino acids of hemoglobin as carbaminohemoglobin in the RBCs.
e-lub [12.9K]

Answer: True

Explanation:Carbon dioxide is transported is transfer in 3 basic ways to human cells.

About 20 % of C0 2 is transported as Carbaminohemoglobin to reach the lungs carbon dioxide binds directly to the amino acid moieties on the globin portions of the haemoglobin to form carbaminohemoglobin. This is a reversible reaction as shown below.

                                        CO2 + Hb ↔ HbCO2.

The reversible binding of C02 to the haemoglobin is due to the   the partial pressure of carbondioxde. In  the  lungs the partial pressure of C02 is low. Therefore C02 is unbounded from the HB and leaves in the lungs, thus the blood   leaving the lungs for the body tissues has low partial pressure C02. Compare to the blood in the tissues with high partial pressure of C02 from metabolic activities of cellular respiration. The C02 therefore diffuses from the tissues to bind with HB to form Carbaminoheamologbin.

In addition C02 is transported by other means.

1. As bicarbonate 70% of the Co2 in the blood is transported and  bicarbonate buffer.

              CO2 + H2O CA ↔ H2CO3↔H+ + HCO3

2, As  soluble carbon dioxide which  dissolves directly  in to the blood stream; this is about 7-10%
