In the Lock and Key Model, first presented by Emil Fisher, the lock represents an enzyme and the key represents a substrate.ock and Key Analogy. The active site is the binding site for catalytic and inhibition reaction of the enzyme and the substrate; structure of active site and its chemical characteristic are of specificity for binding of substrate and enzyme.
