The lock-and-key model refers to the way in which a substrate binds to an enzyme's active site. Similar to how a key has to be the correct one for a lock, no reaction takes place ...
Definition of Lock and Key Model
Enzymes are complex proteins produced by living cells that catalyze biochemical reactions at different body temperatures. They catalyze chemical reactions by binding substrates to the active site on the enzyme. When the substrate binds to the enzyme, it...
This is often referred to as "the lock and key" model. <sup>:8.3.2</sup> This early model
explains enzyme specificity, but fails to explain the stabilization of the transition
In this analogy, the lock is the enzyme and the key is the substrate. ... explained
by using the so-called rigid enzyme model assumed by the lock and key theory.
... can fit into the enzyme. Just like only one key can open a lock, only one type of
enzyme can speed up a specific reaction. This is called the lock and key model.

Jun 18, 2014 ... The lock and key hypothesis helps explain some of the ways that enzymes work.
In the Lock and Key Model, first presented by Emil Fisher, the lock represents an
