Question

- Define primary and secondary Metabolites.Give examples?​

Answer 1

Answer:

                               A primary metabolite is a kind of metabolite that is directly involved in normal growth, development, and reproduction.It usually performs a physiological function in the organism (i.e. an intrinsic function). A primary metabolite is typically present in many organisms or cells. Examples of primary metabolites include: lactic acid, and certain amino acids.

                              A secondary metabolite is a kind of metabolite that  is not directly involved in those processes, but usually has an important ecological function (i.e. a relational function). A secondary metabolite is typically present in a taxonomically restricted set of organisms or cells (plants, fungi, bacteria, etc). Examples of secondary metabolites include: ergot alkaloids, antibiotics, naphthalenes, nucleosides, phenazines, quinolines,terpenoids, peptides and growth factors
