The upcoming discussion will update you about the difference between constitutive enzymes and inductive enzymes. The enzymes which are always present in the organism in constant amounts regardless of its metabolic state are called as constitutive enzymes. For example, the enzymes involved in central pathway of catabolism such as glycolysis are constitutive enzymes. Sometimes, the en­zymes appear in cells only [...]

Sometimes it has been found that when a series of reactions is catalysed by a number of enzymes in sequence, the accumulation of the final end-product may cause inhibition in the activity of the first enzyme of the series. This inhibition due to a compound (final end product) which is totally different in structure from the substrate of the enzyme [...]
