(2) The enzyme grabs onto the substrate with a special area called the
ACTIVE SITE. The active site is a specially shaped area of the enzyme that fits around the substrate. The active site
is the keyhole of the lock.
(3) A process called CATALYSIS happens. Catalysis is when the substrate
is changed. It could be broken down or combined with another molecule to make something new.
(4) The enzyme lets go. Big idea - When the enzyme lets go, it returns
to normal, ready to do another reaction. The substrate is no longer the same. The substrate is now called the PRODUCT
