When oxygen is transported, it is done as some and 2% dissolved as a __ __ gas in plasma. 98% oxyhemoglobin 32% oxyhemoglobin 75% oxyhemoglobin 98% glucohemoglobin

The correct answer is $98\%$ oxyhemoglobin.<br /><br />Oxygen is primarily transported in the blood by binding to hemoglobin, a protein found in red blood cells. When oxygen binds to hemoglobin, it forms oxyhemoglobin. The majority of oxygen in the blood is carried in this form, with only a small percentage dissolved directly in the plasma.<br /><br />The correct answer is $98\%$ oxyhemoglobin, as this represents the majority of oxygen transport in the blood.
