Gas Transport Mechanism A. Oxygen 1. Very low solubility in blood B. Carbon Dioxide 2. Bound to hemoglobin (HbO2) C. Carbon Monoxide 3. As bicarbonate ions D. Nitrogen 4. Dissolved in plasma

Options

  1. AA-3; B-2; C-4; D-1
  2. BA-2; B-3; C-4; D-1
  3. CA-2; B-4; C-3; D-1
  4. DA-2; B-3; C-1; D-4

Correct answer

B. A-2; B-3; C-4; D-1

Step-by-step solution

Oxygen is mainly transported bound to hemoglobin (HbO2). Carbon dioxide is mostly transported as bicarbonate ions. Carbon monoxide is dissolved in plasma. Nitrogen has very low solubility in blood.
