uestion 4 of 15 Incorrect ncorrect Mapo Sapling Learning macmillan learning Which of the following statements about hemoglobin and myoglobin structure are true? Select the five true statements. Hemoglobin is a heterotetramer, whereas myoglobin is a monomer. 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. wich iron atom can form six coordination bonds: One of these bonds is formed between iron and xygen Each hemoglobin or myoglobin molecule can bind four oxygen molecules. Molecular oxygen binds irreversibly to Fe2* in heme. Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron atom.

Solution

6th option is false.. molecular oxygen binds irrevesibly to fe heme.

4th option is true.
