(d) Single circulation system

The main role of the protein hemoglobin is to transport oxygen. Red blood cells use hemoglobin to pick up oxygen from the lungs and then drop it off at subsequent cells. Blood also carries sugar (glucose) around the body. Glucose is picked up in the intestine and dropped off subsequent cells. When an individual has sickle cell anemia, blood does not flow properly and oxygen and sugar are not transported effectively.

Oxygen is picked up in the lungs. The cells of lung tissue are held together with junctions. Which of the following is likely to mediate this junction if liquid cannot pass between the cells in the extra-cellular matrix or directly from cell to cell?

Cadherin

Connexin

Calnexin

Claudin
