9.1 Cellular Respiration

You should be on the purple “Lesson Overview” tab. Click “start” and read through the slides to answer the questions below:

1. How does the food you eat give you energy?

2. The energy stored in food is expressed in units of ___________________________, which is:

3. What is cellular respiration?

4. What is the equation for cellular respiration?

5. If oxygen is available, organisms can obtain energy from food through a process called:

6. What are the 3 main stages of cellular respiration?

1) ____________________________________________

i. About ______% of the energy from glucose is still locked in the chemical bonds of pyruvic acid at the end of glycolysis

2) ____________________________________________

i. True or false: This cycle produces about the same amount of energy as glycolysis does

3) ____________________________________________

i. True or false: This cycle generates most of the energy for cellular respiration by using oxygen

7. The pathways of cellular respiration that require oxygen are called:

8. Which parts of cellular respiration take place in the mitochondria?

9. Which parts of cellular respiration take place in the cytoplasm of the cell?

10. Which parts of cellular respiration are aerobic?

11. Which parts of cellular respiration are anaerobic, and what does anaerobic mean?

12. What is the relationship between photosynthesis and cellular respiration?

13. Cellular respiration takes place in what kinds of organisms?

14. In the list from #13, underline the organisms who engage in photosynthesis.

Now, go to the tab called “Assessments” and do the “Self Quiz”, writing your answers below. Evaluate your own performance J
1. A Calorie (capital C) is

2. Cellular respiration is the process that releases energy from food in the presence of:

3. The 1st set of reactions in cellular respiration is:

4. Which stage of cellular respiration is an anaerobic process?

5. What is a fundamental difference between photosynthesis and cellular respiration?

After you’re done with 9.1, go back to the list of sections and get into the lesson overview for section 9.3 Fermentation.

9.3 Fermentation Lesson Overview

16. How do organisms generate energy when oxygen is not available?

17. What is involved in the process of fermentation?

18. Where does fermentation occur?

19. Without the presence of oxygen, fermentation will occur after ________________________

20. What are some practical applications of fermentation? (What could a person use the process of fermentation for?)

21. Humans can be fermentors too! The human body uses lactic acid fermentation during exercise. Where does your body get ATP for short, quick bursts of energy?

22. How does your body generate ATP for exercise longer than 90 seconds?

23. Why do you breathe heavily after an intense workout?

24. True or false: Fermentation releases energy more slowly than cellular respiration.

25. The body stores energy in the form of this carbohydrate: ________________________, which can last for 15-20 minutes of activity. After this, the body begins breaking down other stored molecules for energy, such as __________________

26. How do animals that hibernate rely on stored energy?

Now, go to the tab called “Assessments” and do the “Self Quiz”, writing your answers below. Evaluate your own performance J

1. What are the two types of fermentation?

2. Fermentation releases energy from food despite the lack of…

3. The process represented by the equation Pyruvic acid + NADH à Alcohol + CO2 + NAD+ is
(No, I won’t expect you to memorize this equation)

4. Why is aerobic exercise an effective way to lose body fat?

5. Runners breathe heavily after a race because their bodies need oxygen to:
