Most Oxygen in the Blood is Transported As

Question

Most oxygen in the blood is transported as
A)deoxyhemoglobin
B)gas dissolved in plasma
C)oxyhemoglobin
D)carboxyhemoglobin
E)carbaminohemoglobin

Accepted Answer

Hemoglobin in red blood cells binds to oxygen to form oxyhemoglobin, which is the main way oxygen is transported in the blood. Deoxyhemoglobin is hemoglobin without any oxygen bound to it, and carboxyhemoglobin is hemoglobin with carbon monoxide bound to it, which can be dangerous. Gas dissolved in plasma and carbaminohemoglobin also play minor roles in oxygen transport.
