LT10

Term 1: Enzyme
Definition 1: A biological catalyst that speeds up chemical reactions without being consumed in the reaction.
Term 2: Substrate
Definition 2: The specific molecule upon which an enzyme acts.
Term 3: Active Site
Definition 3: The region of an enzyme where the substrate binds and where the chemical reaction occurs.
Term 4: Enzyme-Substrate Complex
Definition 4: The temporary complex formed when an enzyme binds to its substrate.
Term 5: Lock and Key Model
Definition 5: A model illustrating that enzymes and substrates possess specific complementary geometric shapes that fit exactly into one another.
Term 6: Induced Fit Model
Definition 6: 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.
