WebDec 9, 2024 · When did Daniel Koshland propose the induced fit model? Daniel Koshland offered a solution to this puzzle in 1958. The induced-fit model is actually an offshoot of an earlier theory proposed by Emil Fischer in 1894, the lock-and-key model. The lock-and-key model states that the substrate acts as a ‘key’ to the ‘lock’ of the active site. WebApr 5, 2024 · The induced fit theory mentioned by Daniel Koshland in 1958. It is the more agreed model for enzyme-substrate complex comparison to the lock-and-key model. In the lock-and-key model, the interaction of the substrate and the enzyme is likened to a key (the substrate) that is highly specific to the lock (the active site of the enzyme).
