1) Aerobic respiration is when Oxygen, the receptor molecule, at the end of a bond breaking process, receives diminished electrons. These electrons have been diminished because as the electrons shift from one molecule to another, they lose some of their energy, often as heat. If the electron receptor is an inorganic molecule other than oxygen, this very same process is called anaerobic respiration. If the receptor molecule is an organic molecule, the process is called fermentation. 2) C 6 H 12 O 6 + 6CO 2  6CO 2 + 6H 2 O + ENERGY In this reaction, Carbon and Hydrogen are oxidized while Oxygen is reduced. This is because of Oxygen’s high electronegativity in relation to that of carbon and hydrogen. Oxygen pulls the electrons away from the carbon and thus is said to be an oxidizing agent. Because the glucose is oxidized, and the electrons which were primarily in equal distance in C-H bond form move closer to one atom, especially as the electrons lose energy along the electron transport chain, this leads to an overall oxidative environment
