What is the biological importance of the heme complex?

The importance of the heme complex, which is a complex of Fe and a tetradentate porphyrin ligand, is that it is part of the protein myoglobin and is responsible for binding to O2 through its Fe cation, since it has one available space to after being bound to the tetradentate porphyrin and one histidine. Four myoglobin units form hemoglobin, which in total carries 4 O2. It's in blood and carries oxygen to the tissues though I don't know if you need to know that

The Heme complex is an example of a biological coordination compound, which makes up hemoglobin and myoglobin. Both of these molecules use their heme complexes to bind and release O2 depending on environmental conditions, which is what oxygenates your organs and muscles.

So Fe cation bonds to O2? Is this what allows the more than one complexes to be bonded?

The heme complex consists of the central Fe atom and four CN groups; when the heme complex binds to a protein it forms hemoglobin, which helps in oxygen delivery throughout the body. Myoglobin is made up of several hemoglobin structures.

How many Oxygen does it take to make hemoglobin?
