enzymes are known as
______________ catalysts. the
enzyme has an ______________
which the substrate molecule is able
to fit into. the substrate molecule is
said to have a
______________ shape to the
enzymes active site. enzymes are
said to be ______________ to just one
______________ for this reason.
when the substrate and enzyme
molecules temporarily combine it is
known as an enzyme - substrate
______________. as the enzyme holds
the substrate molecule in a certain
way it puts tension on the substrate
molecule. this lowers the
______________ energy needed for
the reaction to take place. this is why
reactions can occur at relatively ____
temperatures in living things.
during the reaction the substrate is
turned into ______________. this is
released from the enzymes active
site and the enzyme molecule is left
______________ and free to
______________ more reactions.
each reaction in our body involves a
specific enzyme. we have
______________ of different
enzymes in our body.

Explanation:

Enzymes are biological catalysts. They have an active - site where the substrate fits (complementary shape). They are specific to a substrate. The enzyme - substrate complex lowers activation energy, allowing reactions at low temperatures. The substrate is turned into a product and the enzyme remains unchanged to catalyze more reactions. Our body has thousands of different enzymes.
