WebEnzyme has a specific site called the active-site where substrate molecules bind to form enzyme-substrate complex. The shape of the active-site is so specific that only substrate which has a complementary shape can fit in. This is called lock and key mechanism and suggests that one enzyme can only catalyse one reaction. WebWhen an enzyme binds its substrate it forms an enzyme-substrate complex. Enzymes promote chemical reactions by bringing substrates together in an optimal orientation, thus creating an ideal chemical environment for the reaction to occur. The enzyme will always return to its original state at the completion of the reaction. crypto exchange websites
