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 ... WebMay 28, 2024 · In the lock and key model, the enzyme and the substrate have three-dimensional shapes that fit each other. The induced fit model proposes enzyme molecules can change their shape, depending on the interaction with the substrate. In this model, the enzyme and sometimes the substrate change shape as they interact until the active site …
