Catalysts speed up these reactions, and do not get “used up” in the
process.

Enzymes work by lowering the activation energy of a reaction, which is 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.

The rate of enzyme function depends on the concentration of the substrate (the reactant) and
the environment of the enzyme.

Enzymes work best under environmental conditions specific
to the enzyme.
Ex: The optimum pH for β-amylase is 4.0–5.0, but the optimum pH for
α-amylase is 6.7–7.0.

Environmental conditions include pH and temperature.

CLO: I can explain in writing the function of enzymes as catalysts.
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.
