The lock-and-key mechanism refers to


The Lock-and-Key model represents enzyme-substrate interactions, suggesting that the enzyme and substrate have specific geometric forms that precisely match each other. They are precise. They must be bound to a specific substrate before they can trigger a chemical reaction.

Explain the mechanism of the lock and key.

The mechanism of the lock and key is a metaphor that describes the uniqueness of an enzyme’s active site and substrate. Just as certain keys act as locks and only certain substrates are compatible with the active site of the enzyme. When the suitable substrate is bound onto the enzyme’s active site, an Enzyme substrate is created. The enzyme catalyzes the reaction, which results in an Enzyme products complex getting created, and then the products are released. The enzyme can be repeated to catalyze different reactions.

The Lock-and-Key theory, first proposed by Emile Fisher in 1894, shows the excellent specificity and specificity of enzymes.
