WebDec 30, 2024 · The lock and key model posits that enzyme active sites function as a lock and their substrates function as a key. When the key is inserted into the lock, the lock turns (i.e., the... WebThe Lock and Key model explains that the enzyme needs to bind substrate, but once the reaction progresses to the transition state and product formation, the active site would not be able to accommodate this change.

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 … WebIn the lock and key model, no structural rearrangements occur upon ligand interaction and binding. In the induced fit model, the ligands bind the receptor in a weak conformation, inducing afterwards a conformational transition towards the tight conformation to maximize favorable interactions.
