The respiratory protein hemocyanin _______.
- a. contains iron
- b. occurs only in vertebrates
- c. transports oxygen in some invertebrates
- 1. d.. colors hemolymph red
Concept introduction: Hemocyanin is the protein present in the blood plasma of arthropods and molluscs which contain copper. The respiratory function of hemocyanin is similar to the hemoglobin in vertebrates. The molecular structure and mechanism of hemocyanin differs from hemoglobin. Hemocyanin is made up of many individual subunits. Each individual subunit in the hemocyanin contains two copper atoms, and it can bind one oxygen molecule.
Reason for the correct answer:
Hemocyanin contains two copper atoms that reversibly bind a single oxygen molecule. Hemocyanins are not bound to blood cells but are suspended directly in the lymph. They transport the oxygen throughout the bodies of some invertebrate animals.
Option c. is given as “transports oxygen in some invertebrates”. As hemocyanin transports oxygen in some invertebrates, option c. is correct.
Reasons for the incorrect answers:
Option a. is given as “contains iron”.
Hemocyanin is a metalloprotein, which consists of two copper atoms and where there is no iron content...
