Section 2.4
Chemical Reactions & Enzymes
Learning Target
I will be able to…
• explain why enzymes are important to living things.
p. 50
Chemical Reactions
Chemical reaction = changing or transforming one chemical into
another by rearranging atoms
Parts of a reaction:
• Reactants = chemical that enter
into a reaction.
• Products = elements or compounds
produced by a chemical reaction.
Na + Cl
Sugar + flour +
eggs
NaCl
p. 50
Energy in Reactions
Chemical reactions need energy.
Sources of Energy:
• Plants store energy from sunlight.
• Animals get energy from consuming plants & other animals.
Activation Energy:
• The energy needed to start a reaction.
p. 51
Enzymes
What role do enzymes play in living things and what affects their
function?
• Catalyst = substance that
speeds up the rate of a
chemical reaction by
lowering the activation
energy.
• Enzyme = proteins that act
as biological catalysts.
• Occurs 10 million x faster.
p. 52
Enzymes
Enzyme structure:
• Enzyme Substrate = place
where enzymes work.
p. 53
Catalase Lab
Be sure you have a copy of the lab packet.
Catalase Lab:
• Read through the packet
