Detailed explanation-1: -A Lock and Key analogy may be used to describe the fundamental action of a single substrate enzyme. In this case, the enzyme is the lock, and the substrate is the key. Only the correct size key, which is the substrate, enters the keyhole, which is the active site of the lock, which is the enzyme.

Detailed explanation-2: -[The term catalytic mechanism refers to the process whereby enzymes and substrates undergo transformation during catalysis.]

Detailed explanation-3: -enzymes. …and enzyme, called the “key–lock” hypothesis, was proposed by German chemist Emil Fischer in 1899 and explains one of the most important features of enzymes, their specificity.
