7.3 Mechanism of Enzyme Action
Enzymes catalyze reactions through a specific mechanism involving an active site. The substrate binds to the active site to form an Enzyme-Substrate (ES) complex. The enzyme then catalyzes the conversion of the substrate into product, forming an Enzyme-Product (EP) complex. Finally, the EP complex b
