WebThere are two types of mechanisms involved to explain substrate-enzyme complex formation; lock and key theory (template model), and induced-fit theory. (i) Lock and Key Theory: Emil Fischer (1894) explained the specific action of an enzyme with a single substrate using a theory of Lock and Key analog (Fig. 12.11). WebBiochemistry and Molecular Biology Education, ... students must understand the various binding sites on an enzyme and be able to reason from simplistic lock and key or induced fit models to the more complex energetics model of transition state theory.
