Explanation:
Detailed explanation-1: -The shikimic acid pathway is responsible for the production of vitamins and aromatic amino acids such as phenylalanine, tyrosine, and tryptophan. It is also a source of precursors which are converted to an array of natural products.
Detailed explanation-2: -A key branch-point compound is chorismic acid, the final product of the shikimate pathway. The shikimate pathway is described in this chapter, as well as factors that induce the synthesis of phenolic compounds in plants.
Detailed explanation-3: -The seven enzymes involved in the shikimate pathway are DAHP synthase, 3-dehydroquinate synthase, 3-dehydroquinate dehydratase, shikimate dehydrogenase, shikimate kinase, EPSP synthase, and chorismate synthase.
