Here's what I get
Explanation:
Each iron atom can form six coordination bonds. One of these bonds is formed between iron and oxygen.
TRUE
By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of the iron atom.
TRUE
Molecular oxygen binds irreversibly to Fe²⁺ in heme.
False. It binds reversibly with heme.
Heme is composed of an organic protoporphyrin component and a metal atom.
TRUE
Hemoglobin and myoglobin are heterotetramers.
False. Hemoglobin is a tetramer. Myoglobin a monomeric protein.
Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron atom.
TRUE
Each hemoglobin molecule can bind four oxygen molecules; each myoglobin can bind only one oxygen molecule.
TRUE
