When a substrate binds an enzyme, the enzyme shifts its shape a little bit to better interact with the substrate. The term that BEST describes this alteration of enzyme-substrate shape is:.

Induced fit

Explanation:

The induced fit model was proposed to describe enzyme-substrate interaction.

The induced fit model proposes that when the active site of an enzyme binds to a substrate, it changes it conformation (shape).

Another model used to describe enzyme-substrate interaction is the lock and key model which suggests that enzyme and substrate are like complementary shapes and when the bind they fit into each other.
