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 ... 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.
