Question

"Tryptophan self-controls its synthesis." Justify this statement

Answer 1

If a lesser amount of Tryptophan is present in a cell, Tryptophan acts as an inducer and binds to a repressor, leading to the synthesis of enzymes required for its production and thus its synthesis.

Answer 2

If an excess amount of Tryptophan is present in a cell, Tryptophan acts as a promoter, preventing the further synthesis of necessary enzymes for its production and thus its synthesis.

Answer 3

If an excess amount of Tryptophan is present in a cell, Tryptophan acts as a co- repressor, preventing the further synthesis of necessary enzymes for its production and thus its synthesis.

Answer 4

tryptophan acts as a repressor in high concentrations

Answer 5

The most correct answer above is that of xcross 5. Tryptophan is a corepressor. This is called feedback inhibition when a product turns off the pathway that makes it.
