7. There are two types of respiration.
Aerobic Cellular Respiration
Fermentation (anaerobic)

8. Aerobic Cellular Respiration
Occurs when cells convert chemical energy, using oxygen, into ATP which is energy that can be used in cellular activities.

9. Aerobic Cellular Respiration
C6H12O6 + 6O2  6CO2 + 6H2O
sugar oxygen carbon dioxide water
Sugar and oxygen are used to make energy.
Occurs in all organisms that need oxygen to survive.
This is called AEROBIC respiration.

10. This process is chemically opposite to photosynthesis.
Cellular Respiration
C6H12O6 + 6O2  6CO2 + 6H2O
sugar oxygen carbon dioxide water
This process is chemically opposite to photosynthesis.
6CO2 + 6H2O  C6H12O6 + 6O2
carbon dioxide water sugar oxygen

11. Cellular Respiration VS Photosynthesis
C6H12O6 + 6O2  6CO2 + 6H2O
sugar oxygen carbon dioxide water
6CO2 + 6H2O  C6H12O6 + 6O2
carbon dioxide water sugar oxygen
Which is which? How do you know?

12. Cellular Respiration C6H12O6 + 6O2  6CO2 + 6H2O
sugar oxygen carbon dioxide water
Cellular respiration uses sugar and kicks out energy in the form of ATP
Photosynthesis takes in light energy to make sugar
6CO2 + 6H2O  C6H12O6 + 6O2
carbon dioxide water sugar oxygen

13. Cellular Respiration Occurs in eukaryotes in the mitochondria.

14. Cellular Respiration
Mitochondria are known as the “Power House” of the cell.
Mitochondria produce all the energy needed by the cell in the form of ATP.

16. Cellular Respiration
Cellular respiration is a process that releases energy in molecules to parts of cells that need the energy.

17. Cellular Respiration
AMP – Adenosine monophosphate has one phosphate group and a small amount of energy

18. Cellular Respiration
ADP – Adenosine diphosphate has two phosphate groups and a little more energy.

19. Cellular Respiration
ATP – Adenosine triphosphate has three phosphate groups and a large amount of energy.

28. Cellular Respiration

29. Cellular Respiration
The entire process kicks out 38 ATP’s but since two are used, there is a net balance of 36.

30. Cellular Respiration
This type of respiration is called AEROBIC RESPIRATION because it requires oxygen.
C6H12O6 + 6O2  6CO2 + 6H2O
sugar oxygen carbon dioxide water

31. Carbon Cycle

32. Anaerobic Respiration
Anaerobic respiration: occurs when cells convert chemical energy, using no oxygen, into ATP which is energy that can be used in cellular activities. There are two types of anaerobic respiration called fermentation.

33. Fermentation
Fermentation: occurs when cells convert chemical energy, using no oxygen, into ATP.

34. Fermentation
Not as efficient because only 2 ATP’s are made instead of the 36 produced by aerobic respiration. (Which would you rather have; $2 or $36?)

35. Fermentation
Because aerobic respiration is more efficient, more organisms that can use oxygen exist than anaerobes even though anaerobes were here first.

36. Fermentation
Entire process occurs in the cytoplasm, not in the mitochondria Since mitochondria are not needed, this process can occur in many types of prokaryotes (bacteria).

37. Fermentation Two types of fermentation: Lactic Acid Fermentation
Occurs when muscles are using oxygen faster than they can get it.
Causes muscle fatigue because of the build up of lactic acid

38. Fermentation Muscle cramps results when lactic acid builds up.

39. Fermentation
Coaches tell athletes to keep walking until they stop breathing hard. This allows the circulatory system to remove the lactic acid from the muscles before cramps start. (usually)

40. Fermentation Two types of fermentation: Alcoholic Fermentation
Occurs when yeast breaks down sugar.
Waste products are alcohol and CO2
Used to make alcoholic beverages, ethanol fuel, and bread.

41. Fermentation
Alcoholic fermentation makes alcohol and CO2 as waste products. Example: bubbles in champagne.

42. Fermentation
Alcoholic fermentation makes alcohol and CO2 as waste products.
Example: CO2 bubbles makes bread rise.
