Answer

(e) Enzyme repression (f) Feedback inhibition (a) Catabolite repression (c) Enzyme induction (d) Repressor (b) Operon

Work Step by Step

The following are some of the metabolic regulation terms with their corresponding description: Enzyme repression- Presence of an an abolic product inhibits its further synthesis by inactivating its operon; Feedback inhibition- End product of a biochemical pathway directly inhibits the first enzyme in the pathway; Catabolite repression- Presence of preferred nutrient represses synthesis of enzymes that would be used to metabolize an alternative substance; Enzyme induction- Presence of a substrate induces the activation of a gene that produces the corresponding enzyme needed for the catabolism of this specific substrate; Repressor- A protein that binds to the operator preventing transcription of adjacent genes; Operon- Sequence of closely associated genes and regulatory sites that regulates enzyme production;
