Cell: Proteins and Polypeptides...
3. Proteins
Step-by-step explanation:
All the bio-molecules in body are made up of several kind of components. In cell the 50% dry weight is proteins. So, the polymeric peptide chains of proteins are found in cells of body.
The crucial foods for the formation and synthesis of bio-molecules are those that are enriched in proteins. Without proteins, the formation of cells in body ceases due to abrupt mitosis process.
