1. Cellular Respiration

3. It’s all a Scandal, really…

4. Where
In mitochondria

5. Reactants O2
Glucose (C6H12O6)

6. Products
CO2
H2O

7. Purpose
To make ATP from the energy stored in glucose

8. Formula:

9. Totals Gycolysis 2 ATP Krebs Cycle 2 ATP
Electron Transport Chain 32 ATP
Total = 36 ATP
36 ATPs = A whole lot of ENERGY from 1 glucose!!!

10. Fermentation
Releases energy from glucose without the presence of oxygen.
There are two types of fermentation: alcoholic and lactic acid.
Alcoholic fermentation is done by yeasts and some microorganisms. It produces alcohol & Carbon Dioxide
Lactic Acid is produced by muscles during rapid exercise when the body cannot supply enough oxygen.

11. Fermentation
Alcoholic Fermentation
Lactic Acid Fermentation

12. Energy & Exercise
Quick energy – Lactic Acid fermentation is used to get quick energy and gives off lactic acid as a by product, thus the muscle pain.
Long-Term Energy – Use cellular respiration to produce energy. Exercising or activities that last for at least 15 to 20 minutes. Best form for weight control.

Equation
Sun “E” + 6CO2 + 6H2O  C6H12O6 + 6O2
C6H12O6 + 6O2
6CO2 + 6H2O + “E” (ATP)
