How does an enzyme recognize its substrate?

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. http://www.columbia.edu/itc/chemistry/chem-c2407/hw/ENZYME_KINETICS.pdf
