About The Lock and Key Model The 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 an enzyme. WebThe lock-and-key model is the earliest and also the simplest model to explain molecular recognition in enzyme actions. It was first proposed by Fischer in 1894. 11 The lock-and-key model assumes that the enzyme (lock) recognizes the substrate (key) through the shape complementarity between the enzyme’s active site and the substrate.
