This is a complicated question, iron is used in our body for many chemical interactions that are needed for cellular and bodily function! However, in general, iron aids enzymes in carrying out many interactions that involve the transport or recruitment of oxygen.

Most notably, iron participates in what are called "heme" groups. These groups are essential for the protein hemoglobin to perform its duty. Hemoglobin is used in red blood cells, which transport and deliver oxygen throughout the body in the bloodstream.

Heme groups are also very important in the electron transport chain, our main source of ATP. Think of ATP as the cell's gasoline, it is used to fuel reactions in the cell and keep it functioning.

So, iron is SUPER important in our everyday life and is used in some of the most important chemical reactions in our body.
