1) Where does oxidative phosphorylation take place? A: Oxidative phosphporylation, TCA cycle, and the electron transport all take place in the mitochondria in animal cells. 2) NADH and FADH pass their electrons to what molecule and what is the product of this reaction? A: Oxygen. This produces H2O and a proton gradient 3) What does NADH-Q oxidoreductase do? 4) What does succinate –Q reductase do? 5) What does 1-cytorchrome C oxidoreductase do? 6) What is cytocrhome C? 7) How are redox potentials related to ΔG°? How would you calculate delta G for a reaction? A: Delta G = -nF delta E. Where n = the number of electrons being transferred. And F = 23kCal/mol/V) You add up all the delta Es and then put that number in the equation above. 8) Along the oxidation phosphate pathway, does the E of the complexes increase or decrease? A: It increases, because these new complexes are less likely to reduce something and become more likely to oxidize something. 9) What does Coenzyme Q do? A: It can carry two electrons, one on each oxygen. When one electron is there, it’s a semiquinone intermediate 10) What is so special about iron-sulfur clusters? A: they participate in oxidation, reduction reactions and are able to take on and give up electrons easily. 11) Be able to describe the mechanism of cytochrome oxidase
