What Is Protein For?

Protein in people is important for muscles, but also an important part of other things in our body like enzymes.  Enzymes are proteins in our body and are important part of making chemical reactions occur in our body.  Without enzymes, reactions in the human body would occur so slowly that it really wouldn't be useful.  These reactions are important part of many processes like making energy, making cells in our body, etc.

Protein helps build up your muscles.
