Distinguish between the transport of CO2 and O2 in the blood by explaining the roles of oxyhemoglobin, carbaminohemoglobin, reduced hemoglobin, and bicarbonate ions Oxyhemoglobin in the red blood cells carries most of the oxygen from the lungs to the tissues. When the respiratory pigment hemoglobin gives up the hydrogen ions it has been carrying it is called deoxyhemoglobin and can more readily take up oxygen to become oxyhemoglobin. Carbaminohemoglobin in the red blood cells carries a small amount of carbon dioxide from the tissues to the lungs. Carbaminohemoglobin is formed when hemoglobin takes up CO 2. Bicarbonate ions are the forms in which most of the carbon dioxide is transported in the blood plasma from the tissues to the lungs. Carbon dioxide combines with water to form carbonic acid which dissociates to hydrogen ions and bicarbonateions. The globin portion of hemoglobin combines with excess hydrogen ions produced by the reaction and becomes reduced hemoglobin . The following substances found in the plasma will cause an increase in the rate of air intake
