2. Describe the relationship between a monomer and polymer.

When you chew your food for some period of time you might notice changes in the taste, even enhancement. Let’s think about chewing a cracker for a moment. Upon chewing the cracker, you’ll notice it becomes sweeter over time.

Use the diagram to explain the relationship between a polymer (starch), an enzyme (amylase), and the monomer (maltose).

The boulder needs a big push at first because…

Sentence Starter:

Think about the boulder example. Why does the boulder need a big push at first, but then no push at all once it’s over the hill? How is this similar to the energy needed to start a chemical reaction?

Prompt:

Turn n Talk

• Claim: I (agree/disagree) that enzymes are not important because…
  
  

• Evidence: For example, enzymes __________.
  
  

• Reasoning: This shows that enzymes are important because __________.

Criteria for Success

Some people say that enzymes are not important because chemical reactions would still happen without them. Do you agree or disagree? Defend your position using what you know about enzymes, substrates, and activation energy

Prompt:

Turn n Talk

• reactant

• product

• activation energy

• with enzyme

• without enzyme

How does an enzyme impact activation energy?

Open Ended

Describe the effect enzymes have on the rates of chemical reactions, such as those occurring inside animals during hibernation.

Open Ended

Predict what would occur to the rate of the chemical reaction if the enzyme changes shape.
