Question

Quizplus · Accepted Answer

Hemoglobin and hemocyanin both have the ability to transport oxygen, but they differ in the types of organisms that they are found in and the way that they bind oxygen. Hemoglobin is found in vertebrates and some invertebrates, and it binds oxygen using iron atoms. Hemocyanin, on the other hand, is found in some invertebrates like crustaceans and mollusks, and it binds oxygen using copper atoms.
