WebNov 22, 2024 · The lock and key model also called Fisher’s theory is one of two models which describe the enzyme-substrate interaction. The lock and key model assumes that the active site of the enzyme and the substrate are equal shaped. It supposes that the substrate fits perfectly into the active site of the enzyme.

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. 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 …
