What are the ways oxygen is transported in the blood, ranked according to the way that is responsible for the majority of transport of oxygen? a. 1-dissolved in plasma, 2- Hb
b. 1-Hb, 2-HCO3, 3-dissolved in plasma
c. 1- dissolved in plasma, 2-Hb, 3-HCO3
d. 1-dissolved in plasma, 2-HCO3, 3-Hb
e. 1-HCO3, 2-Hb, 3-dissovled in plasma
f. 1- Hb, 2-dissolved in plasma

f. 1- Hb; 2- dissolved in plasma

Explanation:

Transport of oxygen in the body occurs in two way; oxygen bound to hemoglobin and oxygen dissolved in plasma.

1. Bound to hemoglobin :

Hemoglobin, or Hb, is a protein molecule found in red blood cells and is responsible for the colour of red blood cells. It is composed of four subunits of two types of the protein globin: two alpha subunits and two beta subunits. Each subunit surrounds a central heme group (red in color) that can bind one oxygen molecule.Therefore, each hemoglobin molecule can bind and transport four oxygen molecules. About 98.5% of oxygen is transported in the body bound to hemoglobin.

2. Oxygen is only fairly soluble in blood plasma. As a result, only 1.5 percent of oxygen in the blood is dissolved and transported in blood plasma.
