WebIn contrast, the induced fit model proposes that the active site of the enzyme undergoes conformational changes upon binding of the substrate. The substrate binding induces a change in the shape of the active site, allowing for better interaction and catalysis. Web27 aug. 2024 · The induced fit model is a model for the interaction of enzymes and substrates. It states that only the appropriate substrate may cause the active site to align properly, allowing the enzyme to execute its catalytic activity. It also implies that the active site evolves until it is fully bonded to the substrate, at which time the final shape ...
