WebOct 2, 2024 · The lock and key model also called Fisher’s theory is one of two models which describe the enzyme-substrate interaction. The lock and key model assumes that the active site of the enzyme and the substrate are equal shaped. It supposes that the substrate fits perfectly into the active site of the enzyme. WebThe lock and key model proposes that an enzyme is a like lock and a substrate is like a key as only one key can fit a lock, just as only one substrate can fit into the active site of an enzyme.
