Answer:
Enzymes are proteins that catalyze chemical reactions that occur in living things. They accelerate the speed of reactions, which contributes to metabolism. Without enzymes, many reactions would be extremely slow.
Explanation:
Each enzyme is specific to a type of reaction. That is, they only act on a given compound and always perform the same type of reaction. The compound on which the enzyme acts is generally referred to as substrate. The great enzyme-substrate specificity is related to the three-dimensional form of both.
The enzyme binds to a substrate molecule in a specific region called a binding site. For this, both the enzyme and the substrate undergo conformation change for the socket.
They fit perfectly like keys in locks. We call this behavior the Key-Lock Theory.
