WebHemoglobin and myoglobin bind oxygen directly on an iron atom located inside of a heme group. Hemoglobin and myoglobin have similar quaternary structures. Hemoglobin and myoglobin bind oxygen in a cooperative manner. Hemoglobin and myoglobin deliver oxygen in response to the Bohr effect. Correct answer Hemoglobin has a quaternary structure characteristic of many multi-subunit globular proteins. Most of the amino acids in hemoglobin form alpha helices, and these helices are connected by short non-helical segments. Hydrogen bonds stabilize the helical sections inside this protein, causing attractions within the molecule, which then causes each polypeptide chain to fold into a specific …
