Answer:
a) the decomposition products and the polymeric products formed during the process, such as polysaccharides, proteins, nucleic acids, and esters, are called primary metabolites. The common primary metabolites are amino acids, nucleosides, and the enzyme or coenzyme.
Secondary metabolites are compounds that are not required for the growth or reproduction of an organism but are produced to confer a selective advantage to the organism. For example, they may inhibit the growth of organisms with which they compete and, as such, they often inhibit biologically important processes. e.g. lipids, carbohydrates etc
B) Biomacromolecules are large biological polymers, such as nucleic acids, proteins, and carbohydrates, that are made up of monomers linked together.
Examples of Biomacromolecules are Proteins, Nucleic Acids(DNA and RNA), Carbohydrates and lipids
Answer :
☞︎︎︎ Primary metabolites
- They have a key role in growth, development and reproduction.
- They are formed during phase as a result of energy metabolism.
- Examples : Amino acids, nueleotides, Acetic acid, Lactic acid and Vitamins.
☞︎︎︎ Secondary metabolites
- They have no role in Growth, development and reproduction.
- They are formed towards the end of growth phase.
- Ecological importance like (drugs, toxins, pigments etc)
- Examples : Rubbers, gums, cellulose, carotenoids, morphines and erythromycin.
☞︎︎︎Biomacromolecules
Molecules which have size of 800 to 1000 daltons, high molecular weights. They are called Biomacromolecules.

- Biomolecules are termed as Metabolites, micro as well as macromolecules which are either intermediates or products of metabolism.
