What is the equation for cellular respiration?
Where does it take place?
True or False: Only animals use cellular respiration

2. Why?
Glucose
ATP
The Cell

3. So: cells use sugar and oxygen to make carbon dioxide and water
6H2O
6CO2
C6H12O6
+ ATP
So: cells use sugar and oxygen to make carbon dioxide and water
BUT…
Oxygen is not actually necessary. It only makes the whole process more efficient

4. There are actually two types of respiration…
Aerobic respiration: respiration WITH oxygen
Anaerobic respiration: respiration without oxygen

5. Aerobic Respiration Respiration WITH oxygen
Aerobic respiration produces 36 ATP (LOTS of energy)
Occurs in the mitochondria

6. Anaerobic Respiration
Also known as fermentation
Respiration WITHOUT oxygen
Anaerobic respiration produces only 2 ATP (Little energy)
Occurs in the cytoplasm

7. Identify the type of respiration
Aerobic or anaerobic?

8. Identify the type of respiration
Aerobic or anaerobic?

9. Which do you think is more beneficial?
Aerobic respiration or Anaerobic respiration?

10. Cellular respiration occurs in three steps
Step 1: Glycolysis
If oxygen: Step 2: Krebs Cycle, Step 3: Electron Transport Chain

11. Who can do the most pushups in this class?
Why do your muscles burn when you exercise?

12. In humans
Anaerobic respiration is known as lactic acid fermentation. Lactic acid causes the burn

13. In yeast
Anaerobic respiration is know as Alcohol fermentation: produces alcohol

14. Is Chris going through aerobic or anaerobic respiration?

15. Is Chris going through lactic acid or alcohol fermentation?

16. Venn Diagram
Aerobic vs. Anaerobic Respiration What do they have in common? What do they both make? What do they both require? Which step do they have in common? What is different? How much ATP does each make? Where does each take place? What are the two types of fermentation? What are the stages in aerobic respiration that are different from anaerobic?

17. Exit Ticket What does aerobic mean? What does anaerobic mean?
Which type of respirations generates more ATP?

18. Exit Ticket
4. Aerobic respiration involves all of the following except
a. glycolysis.
b. the Krebs cycle.
c. mitochondria
d. lactic acid fermentation
