Enzyme substrate reaction theory
WebSep 8, 2024 · A substrate is the molecule that enzyme acts upon. There are two theories that describe the binding of enzymes: 1) Lock and Key Theory and 2) Induced Fit Theory. 1) Lock and Key Theory: The shape of the enzyme's active site is complementary to that of its substrate. 2) Induced Fit Theory: The active site has a flexibility of shape, thus when … WebAcc. to the lock and key model, the enzyme and its substrate fit together during catalysis like jigsaw puzzle pieces. But this model is not exactly right because it has been seen that only when enzyme and substrate come in close proximity of each other, an induced fit occurs i.e. they change their original conformations a bit to perfectly fit ...
