WebFischer's Lock and key theory. Lock and key theory was proposed by Fisher. According to this theory, first a physical contact is made between the enzyme and the substrate. As only a specific key fits in a particular lock to open it, a specific substrate combines with the active site of specific enzyme. This combination leads to the production ...
