Ans: 4 biomolecules- Carbohydrate, protein, lipid, nucleic acid
1.
Carbohydrate- Monosaccharide is the basic subunit
of carbohydrates.
Example of the large molecule (polymer)- Starch made up of glucose
subunits. Starch serves to store energy in plants.
2. Proteins- Amino acids are the basic subunit of proteins.
Example of the large molecule (polymer)- Collagen plays an important role in cell adhesion, maintaining the infrastructure of tissue.
3. Lipid- Glycerol and fatty acids serve as lipid subunits.
Example of the large molecule (polymer)- phospholipid- It maintains the structural integrity of the plasma membrane.
4. Nucleic acid- nucleotides are the basic subunit of nucleic acid.
Example of the large molecule (polymer)- Deoxyribonucleic acid (DNA)- It is the main genetic material of cell that is inherited from parents to offsprings.
