How Cells Get Energy

Energy Source of Cellular Processes:

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

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