The rate of an enzyme-
catalyzed reaction increases
as the temperature is raised
beyond optimum
temperature.
Many enzymes require the
presence of other
compounds - cofactors -
before their catalytic activity
can be exerted.
if the amount of the enzyme
is kept constant and the
substrate concentration is
then gradually increased, the
reaction velocity will
decrease.
In the Induced-fit Model, if a
dissimilar substance which
does not fit the site is
present, the enzyme rejects it
Oxidases change the
geometry of a molecule
A prosthetic group - an
organic substance which is
dialyzable and thermostable
which is firmly attached to
the protein or apoenzyme
portion.
The enzyme is thought to
lengthen the "path" of the
reaction.
Absolute specificity will act
only on molecules that have
specific functional groups.
Beyond maximum velocity,
increasing the amount of
substrate in the system,
while the enzyme
concentration is constant,
will further increase the
enzyme activity.
Enzyme inhibitors are
substances which either
increase or decrease the
catalytic action of the
enzyme.
