In what form is most carbon dioxide transported in blood?
Answer and explanation
Correct answer: As dissolved bicarbonate
During cellular respiration, carbon dioxide is produced as a waste product. Most of it enters red blood cells, reacts with water, and is converted into bicarbonate ions, which are transported in the blood plasma. At the lungs, the reaction reverses and carbon dioxide is released for exhalation. Therefore option A is correct; oxygen and glucose are different transported substances, not forms of carbon dioxide.
