Cellular Respiration

1. Read the article “Oxidation—One Process, Two Forms” on page 99.

2. Explain the meaning of the article title, i.e. what is Oxidation?

Goal: To explain the cellular respiration by examining two different models and measuring exhaled air for waste gas.

Cellular Respiration

The Chemical Formulas for Oxidation:• Combustion:

CH4(g) + 2O2 (g) + Energy ==> CO2(g) + 2H2O(g)

• Discuss Answers to Questions #5 & #6

Cellular Respiration

The Chemical Formulas for Oxidation:1. Combustion:

CH4(g) + 2O2 (g) + Energy ==> CO2(g) + 2H2O(g)

2. Cellular Respiration: C6H12O6(aq) + 6O2(g) ==> 6CO2(g) + 6H2O(g) ) + Energy

3. Photosynthesis: 6CO2(g) + 6H2O(g) + Sun Light ==> C6H12O6 (aq) + 6O2(g)
