Which of the Following is Not a Means of Transporting

Question

Which of the following is not a means of transporting oxygen in the blood?
A)As oxyhemoglobin
B)Combined with the bicarbonate ion (HCO3-)
C)Dissolved in the plasma
D)All of the above are used to transport oxygen in the blood.

Accepted Answer

Oxygen is transported in the blood primarily through binding to hemoglobin in red blood cells (as oxyhemoglobin) and by dissolving in the plasma. The bicarbonate ion (HCO3-) is involved in carbon dioxide transport rather than oxygen transport.
