what is the name of the place where the reaction occurs on an enzyme?
Active site
what is the name of the molecule the enzyme acts on?
Substrate
what is the name of the molecule produced by the enzyme after the reaction?
product
once the product has left the active site, the enzyme can be re-used.
The lock and key hypothesis states that the enzyme's active site and the substrate have complimentary shapes.
the shape of the active site must match the shape of the substrate to allow it to bind with the enzyme.
enzymes work best at specific temperatures because if too hot or cold, the bonds holding the amino acids together may break down causing the enzyme to denature (lose its shape).
lock and key model suggests that the active site and substrate are complementary in shape so they fit together like a lock and key.
induced fit model suggests that when the substrate enters the active site, the enzyme changes its shape slightly to accommodate the substrate.
