Answer:
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.
