Question
Hemocyanin is an oxygen-transport metalloprotein present in some invertebrate animals. This protein contains:
The correct answer is
two copper atoms
Hemocyanin Composition Explained
Hemocyanin is a copper-containing oxygen-transport metalloprotein found in the hemolymph of many invertebrate animals.
Key Component: Unlike hemoglobin which uses iron, hemocyanin utilizes copper atoms to bind and transport oxygen.
Quantity: Each functional unit of hemocyanin typically contains two copper atoms. These copper atoms are crucial for the protein's ability to reversibly bind oxygen molecules.
Therefore, hemocyanin contains two copper atoms.
