(B) Arthropods and many molluscs have hemocyanin with copper as the oxygen-binding component.
(C) Hemoglobin is involved in the transport of O2 but not CO2.
(D) A small change in the partial pressure of oxygen can result in a large change in delivery of O2.
(E) CO2 produced during cellular respiration lowers blood pH and decreases the affinity of hemoglobin for O2; this is called the Bohr shift.
