Read Gas Transport
A focused NSEB read for the gas transport pattern. Learn the linked concept, then apply it in the source questions.
Gas Transport is the central idea in this question pattern. Identify the condition in the stem before applying the method below.
Gas Transport
Tissue capillary exchange. Oxygen diffuses from blood to tissues at systemic tissue capillaries, so blood loses the most oxygen there.
Hemocyanin
Blue blood supports oxygen transport in some invertebrates. Hemocyanin is a large copper-containing respiratory protein that circulates freely dissolved in the haemolymph rather than inside red blood cells. It can carry multiple O2 molecules because it is a large multimeric protein. Therefore statements A and C are accepted in the official key.
