Chapter 9: Cellular Respiration -What are the three key pathways of respiration? [Glycolysis, citric acid cycle, electron transport/oxidative phosphorylation] -Which is more effiecient: Fermentation or aerobic respiration? Why? [Aerobic respiration. Only in the presence of oxygen can the energy in pyruvate be released] -What is the fuel for respiration? The exhaust? [Food/Organic compoinds/Glucose; Carbon dioxide and water] -What is the chemical equation for the overall aerobic respiration reaction of glucose? [C6H12O6 + 6O2 6CO2 +6H2O + Energy (ATP + Heat) -When do redox reactions release energy? Why? [When electrons move closer to electronegative atoms. Because electrons lose their potential energy] -What is reduction? Oxidation? [reduction: addition of electrons to another substance; oxidation: loss of electrons from a substance] -When oxygen reacts with hydrogen from methane, where are the electrons of the covalent bonds drawn to? Why? [Closer to oxygen; Because it is more electronegative] -During respiration, organic molecules with an abundance of __________ are good fuels [Hydrogens] -What is the significance of transferring electrons to a lower energy state? [Energy is released and becomes available for ATP synthesis]
