WebJr., in 1958 is one of the most fundamental discoveries of our age and is a development of Emil Fischer s well-known lock and key theory,it should be noted that an important characteristic of the key-lock theory is that the enzyme accommodates the substrate without having to change the shape of the active site however, in the induced-fit model ... 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 ... WebTwo models currently exist to explain how an enzyme and its substrate interact. One model, called the lock and key model, suggests that an enzyme is like a lock, and its substrate is like a key. The shape of the active site on the enzyme exactly fits the shape of the substrate. A second model, called the induced fit model, suggests that the ...
