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 ...

WebThe lock-and-key model is the earliest and also the simplest model to explain molecular recognition in enzyme actions. It was first proposed by Fischer in 1894. 11 The lock-and-key model assumes that the enzyme (lock) recognizes the substrate (key) through the shape complementarity between the enzyme’s active site and the substrate. This ...
