Question
In feedback control of metabolic pathways, what role does an auxotrophic mutant play?Question 6Answera.It inhibits the overproduction of intermediatesb.It has no significant role in metabolic regulationc.It increases the production of the end-productd.It allows the overproduction of a metabolite by bypassing a regulatory step
Solution
d. It allows the overproduction of a metabolite by bypassing a regulatory step
An auxotrophic mutant is a microorganism that requires a particular additional nutrient which the normal strain does not. This mutation can occur in a gene that codes for an enzyme involved in the metabolic pathway. When this happens, the mutant is unable to produce that enzyme, which can lead to the accumulation of the substrate or the depletion of the product of the enzymatic reaction in the metabolic pathway. This can bypass a regulatory step, leading to the overproduction
