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 … WebThe lock-and-key model and the induced-fit hypothesis are two potential models for how substrates may bind in the active site of an enzyme. The lock-and-key model suggests that the substrate is completely complementary in shape to the active site, so that it fits in 'perfectly' - i.e. the way a key (the substrate) fits into a lock (the enzyme).). There is no …

WebDec 30, 2024 · The lock and key model posits that enzyme active sites function as a lock and their substrates function as a key. When the key is inserted into the lock, the lock turns (i.e., the... WebIn the lock and key model, the shape of the active site matches the shape of its substrate. molecules.

WebApr 9, 2024 · lock-and-key theory Quick Reference A theory to explain the mechanism of enzymatic reactions, in which it is proposed that the enzyme and substrate (s) bind temporarily to form an enzyme–substrate complex. The binding site on the enzyme is known as the ‘active site’ and is structurally complementary to the substrate (s). WebLock and Key model.
