1. How Cells Get Energy

2. Energy Source of Cellular Processes:

3. Two Pathways Aerobic Respiration Anaerobic Processes
Cellular Respiration
Main route of ATP production
Used by our cells under normal conditions
Oxygen is the electron acceptor
Anaerobic Processes
Fermentation
Used when oxygen is scarce
Method of ATP production in some bacteria, protists, and yeasts

4. Cellular Respiration
The Equation
C6H12O6 + 6O2 6CO2 + 6H2O
