The metabolism can be defined as the sum of all the biochemical reactions carried out by an organism.

Metabolites are the intermediates and products of metabolism and are usually restricted to ________

______are present in every living cell capable of dividing.

__________are present only incidentally and are not of paramount significance for organism’s life

primary metabolism are derived from secondary metabolites

secondary metabolites they do make up basic molecular skeleton of the organism

Its absence does not immediately curtail the life of an organism,

The multitude of ______ secretions is harvested by human kind to improve their health (antibiotics, enzyme inhibitors, immunomodulators, antitumor agents, and growth promoters of animals and
plant)

The major sources of secondary metabolites are 1-plants
2-bacteria,
3-fungi, 4-and many marine organisms

(80% of secondary metabolite),

Conventional : relies on extraction of metabolite, not production,

from the tissues of plant by different phytochemical procedures like solvent, steam, and supercritical extraction.

In vitro : Plant cell and tissue cultures can be established routinely under sterile conditions from explants, such as plant leaves, stems, roots, meristems

Shoot, root, callus, cell suspension, and hairy root culture are used to synthesize metabolite of interest.

The most important building blocks used in the biosynthesis of secondary metabolites are derived from

The shikimate biosynthesis pathway provides precursors for aromatic molecules in bacteria, fungi, and plants

This biochemical pathway is a major link between primary and secondary metabolism in higher plants
