1. Warm ups:
During photosynthesis, plants use carbon dioxide and give off ________.
C6H12O6 is the chemical formula for ____________________.
Photosynthesis only occurs in cells that contain _______________________.
During photosynthesis, plants remove ___________________ from the air.

2. RESPIRATION AND FERMENTATION NOTES
OBJECTIVE: TO DESCRIBE RESPIRATION AND FERMENTATION

3. Getting Energy from Food
1. How do we change food into usable energy?
ANSWERS: Respiration
and
Fermentation

4. Cellular Respiration 2. What happens during cellular respiration?
3. How is the energy is stored?
ANSWER: Food is broken down and energy is released.
ANSWER: ATP molecules

5. Cellular Respiration
4. Where does cellular respiration take place in eukaryotic cells?
5 What must be present for cellular respiration to take place?
4. Mitochondria
5. OXYGEN AND SUGAR (food)

6. Reactants of respiration = oxygen and sugar
Products of respiration = carbon dioxide, water, ATP

7. Formula of Respiration+ +
Glucose
Carbon dioxide +
Oxygen
water
Energy (ATP)

8. Respiration ATP H2O CO2 O2 C6H12O6 water Carbon Dioxide oxygen glucose
energy

9. Anaerobic Respiration
1.What is anaerobic respiration?
2. What does “anaerobic” mean?
ANSWER: When energy still needs to be made, but there is no oxygen
ANSWER:
Without oxygen

10. Anaerobic Respiration
3. Where does anaerobic respiration take place?
Does it create the same amount of ATP?
There are 2 types of anaerobic respiration: what are they?
ANSWER: in cytoplasm
ANSWER: no, less ATP
ANSWER:
Alcoholic
Lactic acid

11. Alcoholic Fermentation
6. What type of organism’s do alcoholic fermentation?
What is the formula?
8. What do we use this process for?
ANSWER: yeast
ANSWER:
Beer and
bread
Glucose alcohol + CO2 + ATP

12. Lactic Acid Fermentation
9. What type of organism’s do lactic acid fermentation?
10. What is the formula?
11. What do we use this process for?
ANSWER: bacteria, yeast, animals
ANSWER:
Wine, pickles, cheese, yogurt
Glucose lactic acid + ATP

13. Lactic Acid Fermentation
12. Did you ever have sore muscles?
13. Why do you get sore muscles?
ANSWER: This happens when your cells don’t have enough oxygen present for cellular respiration then fermentation takes place.
ANSWER: lactic acid gives you sore muscles!

14. Why would fermentation be helpful?
If your body couldn’t get oxygen fast enough, it can still make a little energy.
If a bacteria is living in an environment with no oxygen, it can still survive.

15. Word Definition Picture
Making energy (ATP) from sugar and oxygen
Cellular Respiration

16. Word Definition Picture
Energy a cell can use!
ATP

17. Word Definition Picture
Making a little energy WITHOUT using oxygen
- makes alcohol and lactic acid
Anaerobic
respiration

18. Word Definition Picture
Creates beer and bread,
used by yeast
glucose creates alcohol and carbon dioxide
Alcoholic
fermentation

19. Word Definition Picture
Creates wine, cheese, yogurt and pickles,
used by yeast, bacteria and animals
glucose creates lactic acid and ATP
Lactic Acid
fermentation

20. Word Definition Picture
Waste product of fermentation: makes muscles sore
Lactic acid

21. Sum It Up Respiration and Fermentation both release energy form food.
Respiration needs oxygen.
Fermentation does not need oxygen. Fermentation makes VERY LITTLE ATP, so it’s not as efficient as respiration.
