Hemoglobin is made up of 4 heme molecules surrounding the globin group, forming a tetrahedral structure. The heme molecules contain one atom of iron each and this is the binding spot for each molecule of oxygen through a covalent bond. Therefore, each hemoglobin molecule can have up to four molecules of oxygen attached to them.
The first is the word “theory”, which means something slightly different in everyday speech than it does in science.
