Document Summary
Site of cellular respiration in all eukaryotic cells. Remember oil (oxidation is lost) rig (reduction is gain) Oxygen is reduced, e^- (and h^+) is added. (h=e^- and h^+); hydrogen is one electron and one proton. *organic compounds (like glucose) possess potential energy as a result of the arrangement of electrons in the bonds between their atoms. How is this energy captured? (answer is in further notes) Main driver of all of this is oxygen. Respiration hints aerobic process, meaning oxygen is involved. An electron"s potential energy level is dependent upon how far away it is from the nucleus. The negative charge of the electron is attracted to the positive charge of the nucleus. An electron loses potential energy when it shifts from a less electronegative atom towards a more electronegative one. A redox reaction relocates electrons closer to oxygen (very electronegative), therefore releasing energy, which is coupled to generating. Transfer from fuel to transport chain is mediated by nadh.
