Видео: Difference Between Enzyme Inhibitor And Enzyme Inducer
The key difference between enzyme inhibitor and enzyme inducer is that enzyme inhibitor decreases the activity of an enzyme by binding with the active site of the enzyme. In contrast, enzyme inducer increases the metabolic activity of an enzyme either by binding to it or by increasing the gene expression.
Enzymes are the biomolecules that catalyze biochemical reactions occurring in living cells. They increase the rate of reactions by lowering their activation energies. Substrates bind with the active site of the enzyme and form the substrate-enzyme complex. Then the substrate transforms into the product, leaving the enzyme behind unchanged. Enzyme inhibitors decrease the activity or catalytic ability of an enzyme, binding with the active site of it. In contrast, enzyme inducer increases the activity of the enzyme by binding or by enhancing the expression of the gene that is coding the enzyme.
