1. Respiration PPT
TEACHER NOTES
This PPT was revised June 24, 2008
There is a notes handout for this PPT.

2. Respiration
To Breathe or Not to
Breathe?

3. Respiration
Respiration is the breakdown of
food (glucose) to release energy.
Where does this take place?
Enzymes (catalyst) are special
proteins that control the process of
respiration.
mitochondria

4. Cellular Respiration
Glucose (C6H12O6)
GlycolysisATP
(no O2 present)
Fermentation
Anaerobic
(O2 present)
Oxidative Respiration
Aerobic
ATP
Step One
Step Two
depends on whether Oxygen is present or not
ATP activation
energy to start
the breakdown
of glucose

5. Oxidative Respiration
Aerobic
Respiration
OXYGEN is
present
CO2 H2O

Oxidative Respiration
Aerobic
(O2 present)
36 ATP
Step Two
(if oxygen is present)

6. FERMENTATION
This is anaerobic respiration.
NO oxygen present
Alcohol Fermentation
EX: yeast
ethyl alcohol +
carbon dioxide
Lactic Acid Fermentation
lactic acid
EX: muscles
Step Two
(if NO oxygen is present)
Fermentation
Anaerobic
(no O2 present)
Fermentation
Total ATP
2 ATP

OXIDATIVE Cellular Respiration

C6H12O6 + O2  CO2 + H2O + 36 ATP
glucose + oxygen  carbon dioxide + water + 36 ATP
