Slide 2 - Open vraag
What is a chemical reaction?
A chemical reaction is a process that changes or transforms one set of compounds into another.
Slide 3 - Tekstslide
Reactants Products
Slide 4 - Tekstslide
Important Terms
Reactants - the elements or compounds that engage in a chemical reactions
Products - the elements or compounds produced by a chemical reaction
Slide 5 - Tekstslide
Which are the reactants?

Slide 6 - Quizvraag
Energy!
Every form of life must have a source of energy so it can carry out chemical reactions.
The energy that is needed to get a reaction started is called its ACTIVATION ENERGY.
Slide 7 - Tekstslide
Enzymes
Enzymes are a type of catalyst found in living things. Catalysts, like enzymes, lower the activation energy and, as a result, make chemical reactions go faster.
Slide 8 - Tekstslide
Enzymes bond to reactants called substrates. Each enzyme is specially fitted to each substrate.
Slide 9 - Tekstslide
What are 2 things enzymes do? Lower _________, speed up __________
Slide 10 - Open vraag
pH & Temperature
Changes in pH (amount of acids or bases) and temperature can impact how well an enzyme works.
If the change is large, it can cause the enzyme to "denature" or stop working.
Slide 11 - Tekstslide
Why could having a high fever slow down your body's ability to do chemical reactions?
