Question

The largest amount of $C{O}_2$ is transported by the blood as?

• A. $C{O}_2$ in the plasma
• B. $H_{2}C{O}_3$ in the plasma
• C. Bicarbonate ions in plasma
• D. Bicarbonate ions in the erythrocytes

Answer 1

The correct option is C Bicarbonate ions in plasma

Carbon dioxide produced in the body is transported either in the plasma, in the form of bicarbonate ions or in the form of carbaminohemoglobin. The maximum amount of carbon dioxide is transported in the form of bicarbonate ions formed in the erythrocytes.

So, the correct answer is 'Bicarbonate ions in plasma'.
