Lock and Key Hypothesis

The lock is the equivalent to that of an enzyme while the key is portrayed as the substrate.
Like an enzyme, the lock can be reused many times as it remains chemically unchanged at the end of the reaction. Also, the fact that reactions occur only at the active site, or binding site, is showed as the key only being able to open the lock only at the keyhole, not anywhere else.
The hypothesis also shows the fact that enzymes can only catalyse a specific substrate, showed as the lock, only being able to open with a specific key.
Firstly ,the  substrate will enter the active side of the enzyme .Then , the enzyme will change it shape slightly as the substrate binds .During  this time , the substrate will be broken down . After that, the product will leave the active sides of the enzymes.
