To become bound to hemoglobin for transport in a mammal, atmospheric molecules of oxygen must cross
A) zero membranesoxygen binds directly to hemoglobin, a protein dissolved in the plasma of the blood.
B) one membranethat of the lining in the lungsand then bind directly to hemoglobin, a protein dissolved in the plasma of the blood.
C) two membranesin and out of the cell lining the lungand then bind directly to hemoglobin, a protein dissolved in the plasma of the blood.
D) four membranesin and out of the cell lining the lung, in and out of the endothelial cell lining the pulmonary capillary–and then bind directly to hemoglobin, a protein dissolved in the plasma of the blood.
E) five membranesin and out of the cell lining the lung, in and out of the endothelial cell lining the pulmonary capillary, and into the red blood cellto bind with hemoglobin
