Diagrams 1-4. Chemical reactions involve changes in chemical bonds. A chemical reaction starts with one set

of molecules and turns them into something new by forming or breaking chemical bonds.

Explain what the 'reactants' are in a chemical reaction.

What does the 'arrow' of a chemical reaction represent?

Diagrams 1-4. Chemical reactions involve changes in chemical bonds. A chemical reaction starts with one set

of molecules and turns them into something new by forming or breaking chemical bonds.

What are the molecules called that come after the chemical change?

Diagrams 5-8. Enzymes are important molecules that are involved with chemical reactions in cells. Look at the diagrams to start to understand how enzymes are involved with reactions.

What is another word for the 'reactants?'

Diagrams 5-8. Enzymes are important molecules that are involved with chemical reactions in cells. Look at the diagrams to start to understand how enzymes are involved with reactions.

In order for the reaction to take place with an enzyme, what do the reactants have to do?

Diagrams 5-8. Enzymes are important molecules that are involved with chemical reactions in cells. Look at the diagrams to start to understand how enzymes are involved with reactions.

At the end of the reaction, what does the enzyme do with the products?

Diagrams 9-12. Enzymes work with a specific reaction and are only compatible with specific substrates.

From what you've seen so far, what makes each enzyme different?

Diagrams 9-12. Enzymes work with a specific reaction and are only compatible with specific substrates.

Why is the 'active site' of the enzyme important?

Diagrams 9-12. Enzymes work with a specific reaction and are only compatible with specific substrates.

In diagram 11, explain why no reaction can occur with substrate 1.

Diagrams 9-12. Enzymes work with a specific reaction and are only compatible with specific substrates.

In diagram 11, explain why no reaction can occur with substrate 2.
