Answer
Option A) Bound to hemoglobin
- Oxygen transport in blood occurs by two ways.
1) Bound to hemoglobin : Hemoglobin is a specialized pigement in blood that transport majority of oxygen About 98% of oxygen is transported bound to hemoglobin. - 2) Dissolved in plasma : Only 2% of oxygen is transported dissolved in plasma.
- Hence, Most oxygen is transported in the blood bound to hemoglobin.

104 Homework 6 4. (15 points): Hemoglobin (Hb) is the main oxygen transport protein in the blood. Each hemoglobin molecule can transport four oxygen atoms at a time, one at each of its four iron-based binding sites. The binding of O2 to hemoglobin is a pH-dependent equilibrium, simplified as: Use Le Chatelier's Principle to answer the following questions: a) What form of hemoglobin, HbH" or Hb(Ojle, would be favored in the lungs? What form would be favored in the cells...

D. On the surface of red blood cells there is a passive antiporter than moves bicarbonate and chloride ions in oppòsite directions. Bicarbonate is produced from carbon dioxide and water by the activity of an enzyme called carbonic anhydrase. Chloride as well as several other inorganíc ions have been shown to reduce oxygen affinity by hemoglobin when these anions are bound to the central cavity Why is it important that this transporter is an antiporter? In what circumstances will bicarbonate...
