the amount of energy needed for a
reaction to happen.

Also, enzymes are substrate-specific,
which means that enzymes only work
with certain substrates that will fit in the
active site.

Enzymes work best under
environmental conditions specific to the
enzyme.

4.0–5.0, but the optimum pH for αamylase is 6.7–7.0.

and temperature.

If conditions aren’t right, the rate of
enzyme function decreases. If
conditions are really not right, the
enzyme may not work at all, or become
denatured.

When proteins unfold, they become
denatured.

CLO: I can explain in writing the function of enzymes as catalysts.
Denaturing can be caused when pH is
too high or too low for the enzyme. It
can also happen if the temperature is
too high or too low.
