gezocate Hotmail.com Alzahrani uestion 8 of 16 Sapling Learning Which of the following statements about hermoglobin and myoglobin structure are true? Select the five true statements Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron atom. Heme is composed of an organic protoporphyrin component and a metal atom Each iron atom can form six coordination bonds: Two of these bonds are formed between iron and oxygen. By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevernt oxidation of the iron atom. Molecular oxygen binds reversibly to Fe? in heme Hemoglobin and myoglobin are heterotetramers. Each hemoglobin molecule can bind for oxygen molecules; each myoglobin can bind only one oxygen molecule.
