Question

Molecular oxygen binds irreversibly to fe2 in heme

Answer 1

Answer:

Molecular oxygen binds reversibly to Fe2 in heme. By itself, heme is not a good oxygen carrier. It must be part of a Larger protein to prevent oxidation of the iron atom. Each hemoglobin molecule can bind four oxygen molecules; each myoglobin can bind only one oxygen molecule.

Answer 2

Answer:

-Molecular oxygen binds irreversibly to Fe2 in heme. -Each iron atom can form six coordination bonds: One of these bonds is formed between iron and oxygen. -Each hemoglobin molecule can bind four oxygen molecules; each myoglobin can bind only one oxygen molecule.
