Chapter 9: Cellular Respiration, Harvesting Chemical Energy The principles of energy harvest Cellular respiration and fermentation are catabolic energy yielding pathways Cells recycle ATP they use for work Redox reactions release energy when electrons move closer to electronegative atoms Electrons ?fall? from organic molecules to oxygen during cellular respiration The ?fall? is stepwise during respiration via NAD+ and an electron transport chain The process of cellular respiration Respiration involves glycolysis, Krebs cycle and electron transport Glycolysis harvests chemical energy by oxidizing glucose to pyruvate The Krebs cycle completes the energy yielding oxidation of organic molecules
