1. Harvesting energy: photosynthesis & cellular respiration
Chapter 4

2. Cellular respiration

3. Cellular respiration summary equation
C6H12O6 + 6 O2  6 CO2 + 6 H2O
many steps, many enzymes

4. Cellular respiration (3 steps)
Making ATP with oxygen
Cellular respiration (3 steps)

2. Krebs cycle
3. Mitochondrial e- transport chain

5. Step 1: Glycolysis

6. Step 2: Krebs cycle
In the mitochondrial matrix

7. Step 3: mitochondrial ETC

8. Cellular respiration - know this:

9. Animals extract energy & other valuable chemicals from molecules other than the simple sugar glucose

10. Making ATP without oxygen
Fermentation

11. Two kinds of fermentation
Lactic acid fermentation
Alcohol fermentation

12. Photosynthesis, the big picture

13. Photosynthesis summary equation
6 CO2 + 6 H2O  C6H12O6 + 6O2
many steps, many enzymes

14. Chloroplasts: site of photosynthesis
Chloroplasts have two parts
thylakoids:
stroma:

15. How photosynthesis & cellular respiration are linked

16. Photosynthesis - know this:

17. Also be able to answer these questions
Where does the CO2 come from?
What about the H2O?
Why is O2 made? What is it for?
What is the sugar for?
