  • There are many functions of the protein molecules in living organisms.
  • They play an important role as bodybuilding molecules, as enzymes, as transporter molecules, and many more.
  • Most of the enzymes are made up of the protein molecules and regulate the metabolic process of the living organisms.
  • Certain proteins are present in the plasma membrane of the cells and play an important role in the transport of the substances across the cells, recognition of certain foreign particles, and some other functions.
  • They also play an important role in the immune system.
  • The main storage molecules of energy are carbohydrates and fats so storage of energy is not considered as the major function of the proteins because they do not involve as carbohydrates and fats.
