• Enzymes
– Are a type of protein that acts as a catalyst, speeding
up chemical reactions
1 Active site is available for a
molecule of substrate, the reactant
on which the enzyme acts.
Substrate
(sucrose)
2. Substrate binds to
enzyme.
Enzyme
(sucrase)
Glucose
OH
H2 O
H O
Fructose
4 Products are released.
3 Substrate is converted
to products.
PRE- LAB INFORMATION FOR:
ENZYME ACTION LAB
There is an enzyme called Catalase found in MOST
organisms.
This enzyme has the ability to break down H O
(which is Hydrogen Peroxide)
2
2
Hydrogen Peroxide is toxic to most
living organisms.
H O is naturally produced in organisms
as a by-product of cellular respiration
(when your cells are making energy).

Catalase quickly arrives on the scene
to destroy the Hydrogen Peroxide
before it can do too much damage.
Catalase speeds up the process of breaking down the
Hydrogen Peroxide molecule into water and oxygen.
