LT10

enzyme

A biological catalyst that speeds up chemical reactions without being consumed in the reaction.

substrate

The specific molecule upon which an enzyme acts.

the active site of an enzyme

The region of an enzyme where the substrate binds and where the chemical reaction occurs.

enzyme-substrate complex

The temporary complex formed when an enzyme binds to its substrate.

lock and key model illustrate?

It illustrates that enzymes and substrates possess specific complementary geometric shapes that fit exactly into one another.

induced fit model

A model describing the dynamic interaction between enzyme and substrate where the binding of the substrate induces a conformational change in the enzyme, resulting in optimal fit and enhanced catalytic activity.
