Explanation / Answer
Answer :
Carbohydrates
Specific monomer: Glucose
Specific polymer: Glycogen
Biological function: Carbohydrates are the major sorces of energy for cellular metabolism. Glycogen is the reserved storage polysaccaharide in the animals and hence it is called as animal starch. It is present in high concentration I the liver as well as in muscles.
Proteins
Specific monomer: Amino acids ( all twenty Amino acids)
Specific polymer: Insulin
Biological function: it is a peptide hormone produced by the beta-cells of the islets of Langerhans in response to elevated blood glucose level. Insulin is a hypoglycemic hormone that lowers blood glucose level through various means such as stimulating the uptake of glucose by liver, skeletal muscle and fat tissue and by inhibiting glycogenolysis and gluconeogenesis.
Nucleic acids: Nucleotides
Specific monomers: Deoxynucleic acid (DNA)
Biological Function: DNA is the chemical basis of heredity and regarded as the reserve bank of genetic information. It is responsible for the maintaining the identity of the different species of the organisms.
Lipids/Fats
Specific monomers: fatty acids
Specific polymers: Phospholipids
Biological function: Phospholipids are amphipathic molecules that make up the bilayer of the plasma membrane and keep the membrane fluid
