1. Cellular Respiration
Academic Biology

2. Cellular Respiration
When food is broken down in the presence of oxygen this is called CELLULAR RESPIRATION

3. equation
Water
Carbon
dioxide
Energy
Glucose
Oxygen

4. Aerobic
Aerobic means there is oxygen present.

5. Steps Steps involved in Aerobic Cellular Respiration are: Glycolysis
Krebs Cycle
Electron Transport

6. Aerobic Respiration
Produces a total of 36 ATP

7. Anaerobic
Means With Out Oxygen

8. Fermentation
Occurs when anaerobic conditions are present.

9. Two Types
The two types of fermentation are:
Alcoholic
Lactic Acid

10. Fermentation
Only produces a total of 2 ATP

11. Glycolysis
Means splitting of Glucose
Occurs in the cytoplasm

12. C-C-C C-C-C 4 ATP 4 ADP C-C-C Pyruvic Acid C6H12O6 Glucose C-C-C
2 NAD+
2 NADH

13. NET GAIN
NET GAIN of 2 ATP
2 NADH
2 Pyruvic Acids

14. FERMENTation When NO Oxygen is present Glycolysis occurs first.
Pyruvic acid accepts H’s from NADH.

15. Alcoholic Fermentation
Occurs in yeast
Pyruvic Acid + NADH  alcohol + CO2 + NAD+

16. Lactic Acid Fermentation
Occurs In Human Muscle Cells!
Pyruvic acid + NADH 
Lactic Acid + NAD+

18. Krebs cycle Second Step in Aerobic Respiration
Occurs in the Mitochondria

19. Part 1 C-C-C = pyruvic acid NAD+ NADH CO2 C-C Acetyl-CoA CoA
Coenzyme A = CoA

20. Krebs Cycle C-C C-C-C-C 6C CO2 4C 5C CO2 ATP NADH NAD+ FADH2 NAD+ FAD
ADP
CO2
ATP
NADH
NAD+

21. Krebs Cycle Review Makes CO2 NADH and FADH2 ATP –one ATP per cycle
Each Pyruvic acid goes through the Krebs Cycle
So per glucose molecule 2 ATP are made in this stage.

22. Electron Transport Third Step in Aerobic Respiration
Occurs in the Mitochondria

23. Steps in the E.T.C. 1. FADH2 and NADH deliver H to the E.T.C.
2. H splits into hydrogen ions (H+) and electrons (e-)
3. e-’s are passed from carrier to carrier; energy is released.
32 ATP are made.
4. Free oxygen acts as the final e- acceptor
5. e-’s, H+, and Oxygen combine to form water.
Water used by the body or excreted.
