Question

Quizplus · Accepted Answer

The heme molecule in myoglobin is not a type of protein structure, but rather a type of non-protein molecule that is bound to the protein. Specifically, it is a prosthetic group, which is a non-protein molecule that is tightly bound to a protein and is necessary for the protein's function. In this case, the heme molecule is tightly bound to myoglobin and is responsible for its ability to bind and transport oxygen.
