MOST carbon dioxide released from red blood cells is transported to the lungs as: a) carbamate groups attached to terminal amino groups of the hemoglobin chains. b) CO2 gas dissolved in the blood. c) None of the answers is correct. d) carbonic acid (H2CO3) e) bicarbonate ion (HCO3-)

Step 1
Carbonic acid then dissociates into bicarbonate ions (HCO3-) and hydrogen ions (H+). Bicarbonate ions are transported in the blood plasma, while hydrogen ions bind to hemoglobin. This process is known as the Haldane effect. So, the majority of carbon dioxide is Show more…
