Carbohydrates is used as a energy source. Eg. The carbohydrates glucose is a basic substrate respiration in all living cells. Also used as storage food. In plant ,food is mainly stored in the form of starch and in animals cells, it is in the form of glycogen. Carbohydrates as a component of cell structure .Eg ,cellulose is used to built up cell wall in the plant cell. It also used as a component of nucleic acid. Eg, one of the component of nucleic acid in a pentose sugars that is the deoxyribose in DNA and ribose in RNA.

4. Component of nucleic acids
Lipids
1. Store energy (for longer usage as compared to carbohydrates)
2. Shock absorber (Protect vital organs in case of shock)
3. Cell membrane structural components
4. Precursors of hormones
5. Insulation - prevent heat loss
6. Aid Vitamin (A, D, E, K) absorption
Proteins
1. enzymes and hormones are actually proteins which help to catalyse and regulate biological reactions
2. Structural protein like collagen impart strength to biological structures
3. Protective proteins i.e. Antibodies are integral parts of the immune system
4. Protein like haemoglobin (carry oxygen around the body) has physiological functions
Nucleic Acids (DNA & RNA)- Carry genetic information in the cell
