Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism.
DNA is necessary for the production of proteins as well as the regulation, metabolism, and reproduction of the cell.
Proteins help repair and build your body's tissues, coordinate bodily functions, and allow metabolic reactions to take place.
Structural, storage, hormonal, enzyme, etc.
