WebNov 22, 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. WebSep 2, 2024 · At the moment, two models are used to describe enzyme specificity: (1) The lock and key model. (2) The induced fit model. The enzyme-substrate interaction in …

WebThe lock-and-key model is used to describe the catalytic enzyme activity, based on the interaction between enzyme and substrate. This model considers the lock as an enzyme and the key as a substrate to explain this model. The concept of how a unique distinct key only can have the access to open a particular lock resembles how the specific ... WebOne enzyme is therefore specific to one substrate's chemical reaction, or type of chemical reaction. This theory for the way in which enzymes work is called the lock and key theory.
