Question

Select all statements that correctly describe hemoglobin and myoglobin structure. a.The heme prosthetic group is entirely buried within myoglobin. b.Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron ( Fe ) atom. d.Each hemoglobin molecule can bind four oxygen molecules; each myoglobin can bind one oxygen molecule. d.Molecular oxygen binds irreversibly to the Fe ( II ) atom in heme. Hemoglobin and myoglobin are heterotetramers. e.Each iron atom can form six coordination bonds. f.One of these bonds is formed between iron and oxygen. g.By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of the iron.

Answer 1

Answer:

B, G , E, F.

Explanation:

Hemoglobin is known to be a tetrameric hemeprotein, which is found in the erythrocytes where it binds with oxygen,and then the bound oxygen is transported to parts of the body.

Myoglobin is a monomeric protein that is found in the muscle tissue. Its function is that, it serves as intracellular storage site for oxygen.

It should be understood that, both hemoglobin and myoglobin are hemeproteins with physiological importance of having the ability of binding molecular oxygen.

In this case, it is also known that, the two, that is hemoglobin and myoglobin have a prosthetic group called heme, which is described or known to be a tightly bond, specifically a non-polypeptide unit which is required for biological function of some protein.
