1. Bellwork: 11/28 Put your phone up  Week 11/26-11/30
Explain what happens in photosynthesis
Explain what happens in cellular respiration
How were the subs?

2. Today:
Finish packets from sub
Unit 4, pt. 3 notes

3. Materials
Unit Book

4. This Week: Monday: Sub Tuesday: Sub Wednesday: Cellular Respiration
Friday: Lab

5. Homework
None 

6. Unit IV: Cell Energy

7. Part III: Cellular Respiration

8. What cells use cellular respiration?

9. Where Does Cellular Respiration Occur?

10. Cellular Resp.
Cellular Respiration: process by which mitochondria break down food (glucose) molecules to produce ATP
3 different phases: glycolysis, citric acid cycle and electron transport chain

11. Phases Anaerobic: Oxygen is NOT required Aerobic: Oxygen is required
1st Stage: Glycolysis
Aerobic: Oxygen is required
2nd Stage: Citric Acid Cycle
3rd Stage: Electron Transport Chain

12. Glycolysis Breaks down glucose Creates 2 ATP ANAEROBIC!!
Occurs in the cytoplasm
Where do we get this glucose?
Where do plants get this glucose?

13. Citric Acid Cycle Breaks down glucose Creates 1 ATP AEROBIC
Occurs in the mitochondria

14. Electron Transport Chain
Creates 32 ATP
AEROBIC
Occurs in the mitochondria

15. Efficiency Aerobic process is more effective!
Anaerobic processes can produce ATP for short periods of time in the absence of oxygen
BUT not enough to keep cells alive

16. Chemical Equation C6H12O6 + 6O2 ➜ 6CO2 + 6H2O + ATP Carbon Dioxide
Energy
Glucose
Oxygen
Water

17. Cellular Respiration Photosynthesis
Plants
Sunlight required
Food accumulated
Energy from the sun stored in glucose
Carbon Dioxide taken in
Oxygen given off
Produces glucose & oxygen from carbon dioxide, water and sunlight
2 phases: light-dependent & light-independent
Occurs in chloroplasts & chlorophyll
All living cells, even plants!
Sunlight not required
Food broken down
Energy of glucose released
Carbon Dioxide given off
Oxygen taken in
Produces ATP, water & carbon dioxide from glucose & oxygen
3 phases: glycolysis, citric acid cycle & electron transport chain
Occurs in cytoplasm & mitochondria
