Induced fit theory is a variation of the lock-and-key theory of enzymatic function. It is proposed that the substrate causes a conformational change in the enzyme such that the active site achieves the exact configuration required for a reaction to occur. The overall effect would be a tighter binding for the substrate and enzyme.

WitrynaThe ‘induced fit’ theory did not disregard the 60-year-old ‘lock and key’ model as obsolete; it just required it to flex a little. The idea of enzyme and substrate fitting … WitrynaLock-and-key model is a model for enzyme-substrate interaction suggesting that the enzyme and the substrate possess specific complementary geometric shapes that fit exactly into one another. Enzymes are highly specific. They must bind to a specific substrate before they can catalyze a chemical reaction. In this case, the enzyme is …

Witryna16 wrz 2024 · The lock and key model describes the key as a substrate and enzyme as a lock. It states that only the correct key will fit in the active site on an enzyme for a reaction to take place. It also says that active sites have a specific substrate shape that is rigid and only reacts with the perfectly fitting substrate.
