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. Each hemoglobin or myoglobin molecule can bind four oxygen molecules. Heme is composed of an organic protoporphyrin component and a metal atom. Hemoglobin is a heterotetramer, whereas myoglobin is a monomer. By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of...

Which five statements about hemoglobin and myoglobin structure are true? Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron atom. Each iron atom can form six coordination bonds. One of these bonds is formed between iron and oxygen. Heme is composed of an organic protoporphyrin component and a metal atom. By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of the iron atom....

Hemoglobin consists of four globular proteins, each formed from a polypeptide chain. Each globular protein contains a nonprotein group with an iron ion. This iron ion binds to an oxygen molecule. Thus, every hemoglobin protein can bind four oxygen molecules. Select the correct statement about oxygen transport below. a. Myoglobin transports oxygen through the bloodstream to tissue. b. To carry oxygen, iron must be in its nonheme form. c. Erythrocytes contain abundant myoglobin for transporting oxygen. d. Hemoglobin is found...
