What is the lock and key analogy for enzymes?
The Lock and Key Analogy of Enzymes and Substrates:
Enzymes act as a catalyst in a given chemical reaction (for example, lactase allows lactose to break down into Glucose and Galactose); enzymes lower the amount of energy required to make a reaction occur. There is a key concept to this theory: Enzymes are designed work for only one reaction; there is only one key that fits the lock perfectly.
Without enzymes, our bodies wouldn't be able to handle the amount of heat the reactions that occur inside if there weren't any enzymes (or the reactions just wouldn't occur!
In the Lock and Key Analogy, the substrate (Lactose in the example) is the "key". The key must fit perfectly into the active site that is on the enzyme, or the "key hole in the lock (Lactase is the Lock in the example). The substrate will then break down into its products (which in the example would be the Glucose and Galactose).
This can happen in different ways: 1) two (or more) substrates can bind onto the same active and combine to form one product; 2) one substrate can bind onto an active site and break down to form two (or more) products.
