KNOW THE TYPES OF LIPIDS
• Enzymes– Are a type of protein that acts as a catalyst, speeding
up chemical reactions
Substrate(sucrose)
Enzyme (sucrase)
Glucose OH
H O
H2O
Fructose
3 Substrate is convertedto products.
1 Active site is available for a molecule of substrate, the reactant
on which the enzyme acts.
2. Substrate binds to enzyme.
4 Products are released.
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 H2O2
(which is Hydrogen Peroxide)
Hydrogen Peroxide is toxic to most living organisms.
H2O2 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.
2 H2O2 2 H2O + O2
