Answer:

There are two models for enzyme-substrate interactions: ... The Lock and Key model explains that the enzyme needs to bind substrate, but once the reaction progresses to the transition state and product formation, the active site would not be able to accommodate this change.

Answer:

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.
