How does the lock and key model work? [Updated!]

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).
