Unit 3 Objectives: Energy in Cells: Cellular Respiration
Chapter 6: Cellular Respiration
These sections will be covered
You should read these sections, but don’t need to take notes on
on the reading quiz
them. These are the difficult concepts that we will emphasis in class
6.1-6.3
6.7-6.10
6.6
6.12-6.16
1. How does cellular respiration and photosynthesis fit into the flow of energy throughout an ecosystem
2. List the 3 stages of cellular respiration and where they occur (be specific)
3. Describe how breathing is related to cellular respiration
4. What is NADH and what is its role? What is FADH2 and what is its role?
5. Describe what is occurring in glycolysis
6. Describes what happens in the Krebs cycle (include what happens to pyruvate before it enters the
Krebs)
7. Describe how ATP is made by chemiosmosis in the ETC. Include H+, H+ pumps, locations, ATP
synthase, electron carriers, the roll of oxygen
8. Compare the production of ATP in each stage of cellular respiration
9. What happens to pyruvic acid if oxygen is present? What if oxygen is not present?
10. Contrast aerobic and anaerobic respirations. Include role of oxygen, amount of ATP produced
11. What is the purpose of fermentation and describe 2 types of fermentation giving examples that
12. What are the 2 types of fermentation and what are the products of the different types of fermentation?
13. What is the difference between obligate anaerobes and facultative anaerobes?
14. Are the raw materials for aerobic respiration always glucose? Explain.

Read the introduction to Chapter 6 and answer the following question.
1.
Explain the difference between slow muscle fibers and fast muscle fibers.
2. Could a naturally fast sprinter become a fast marathon runner? Explain.
3. If you have a high percentage of slow muscle fiber, name an activity not mentioned in the article
that you would probably be good at.
4. If you are good at stealing bases in baseball, which type of muscle fiber do you think you have
more of?
5. What is different about the way in which slow and fast muscle fibers process glucose for energy?
6. Who is more likely to get sore muscles, those that have a majority of slow or fast muscle fibers?
Why?
