There are ii views regarding the vogue of activity of enzymes: Lock in addition to Key hypothesis (theory) Induced correspond hypothesis (theory). Lock in addition to Key Theory: Emil Fisher proposed this hypothesis inwards 1894. According to this hypothesis the active site of the enzyme is similar a ‘lock’ into which substrate fits similar a ‘key’.i.e., the shape of the active site in addition to the substrate molecules are complementary . So the enzyme molecule holds the substrate, molecule closed together, forming the unusable intermediate compound, the enzyme substrate complex. It dissociates to shape enzyme in addition to products. Induced Fit Theory: Daniel E.Koshland formulated this hypothesis inwards 1959. According to this hypothesis the active site does non convey a stiff ‘lock in addition to key’ conformation. The binding of the substrate molecule to the enzyme molecule induces to modify the shape of the active site in addition to thence that it becomes compleme
