Which five statements about hemoglobin and myoglobin structure are true? each iron atom can form six coordination bonds. two of these bonds are formed between iron and oxygen. hemoglobin is a heterotetramer, whereas myoglobin is a monomer. both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron atom. each hemoglobin or myoglobin molecule can bind four oxygen molecules. molecular oxygen binds reversibly to fe2+ in heme. by itself, heme is not a good oxygen carrier. it must be part of a larger protein to prevent oxidation of the iron atom. heme is composed of an organic protoporphyrin component and a metal atom.
