24. Think-Write – Pair – Share MCAS Practice
Think & Write: Respond to the following prompt in writing (10 min)
You breathe more heavily when you exercise, right?
Name the cell process that is causing you to breathe heavily
In reference to the process you just named:
What is this cell process producing for your body? How does it do it?
Describe how the things that you breathe in and out are directly related to this cell process.
Why does it happen more rapidly after exercise?
Objectives for Class:
Identify the organelle in the cell where the process of cell respiration occurs
Explain how the body uses food and oxygen to create ATP, Carbon Dioxide and Water

25. Think – Pair – Share/ MCAS Practice
Pair: Pair off and grade your partner’s response (5 min)
It MUST have the following details:
The Process: Cell respiration
This process produces ATP for cells to do work
You need oxygen to produce large amounts of ATP through cell respiration, which happens in the mitochondria (otherwise your cells produce small amounts of ATP in the cytoplasm)
Carbon dioxide is also produced as a bi-product of this reaction
You breathe in oxygen when you inhale (input to cell respiration)
You breathe out carbon dioxide when you exhale (output to cell respiration)
As you exercise, your cells are doing more work and require more ATP
You need to breathe in a lot of oxygen to create all of this ATP through cell respiration, so you breathe in more heavily
Because you are also producing large quantities of carbon dioxide through this process, you need to exhale it an large quantities
This is why you breathe more heavily during exercise…

26. Think – Pair – Share/ MCAS Practice
Share: Compare the graded responses
Come back together with your partner and explain to them how you graded their response.
Identify the details they did not include.
Provide them with 2 ideas to make the response better.
