A structural feature of an enzyme will attach to a specific structural feature of a protein.
Example of lock and key hypothesis. The lock and key hypothesis states that the substrate fits perfectly into the enzyme like a lock and a key would. Like a key into a lock only the correct size and shape of the substrate the key would fit into the active site the key hole of the enzyme the lock. Its difficult to see lock and key in a sentence.
According to this principle if the right key fits inside the right lock the lock will be opened otherwise it will not. Similarly what is the lock and key hypothesis of enzymes. The place where these molecules fit is called the active site.
The place where these molecules fit is called the active site. For example about 1000 enzymes are known to use the coenzyme NADH. The lock-and-key model is the earliest and also the simplest model to explain molecular recognition in enzyme actions.
This is the most accepted of the theories of enzyme action. Learn Biology- Lock and Key Model of Enzyme. The molecules on which the enzymes act are known as substrates of enzymes.
Lock and key hypothesis Enzymes are folded into complex 3D shapes that allow smaller molecules to fit into them. Only the correctly sized key substrate fits into the key hole active site of the lock enzyme. The skeleton is under lock and key.
It states that the shape of the Active Sites of Enzymes are. In this analogy the lock is the enzyme and the key is the substrate. Likewise if the right enzyme fits into the right substrate the drug will form otherwise it wont.
