Hemoglobin differs from myoglobin because
A) it does not have a heme group.
B) it is a tetramer, whereas myoglobin is a single polypeptide chain.
C) it does not contain any helical regions.
D) it contains more β -pleated sheet structure.

Question

Quizplus · Accepted Answer

Hemoglobin is a tetrameric protein, consisting of four polypeptide chains, each with a heme group, allowing it to bind and transport multiple oxygen molecules. Myoglobin, on the other hand, is a monomeric protein, composed of a single polypeptide chain, primarily functioning in oxygen storage in muscle tissues. This structural difference is crucial for their respective roles in oxygen transport and storage.
