Explain the induced fit of an enzyme reaction including what happens to the substrate after the reaction has taken place

The induced fit model explains that the active site of an enzyme changes slightly so that a substrate can fit into it. This is a modification of the lock and key model according to which no changes occurred in the active site of the enzyme.

The induced model explains that the active site undergoes changes to fit the substrate. After the substrate is catabolized or anabolized, it gets detached from the active site. The active site then takes its usual shape back until next substrate arises.
