The functions of protein include building and repair of body tissues, it also helps in maintain a proper potential of hydrogen (PH) for the body. Lastly, protein is also essential for growth as they help in cell and tissue growth.
Enzymes are catalysts that are responsible for speeding the chemical reaction rate in the body cells. Enzymes help in digestion.
