Question

1) Which of the following techniques can be used to quantify protein-protein interactions? A) Co-immunoprecipitation B) Affinity chromatography C) Chemical cross-linking D) Surface plasmon resonance E) The two-hybrid system 10) Arsenic poisoning acts by inhibiting the citric acid cycle at the point of both pyruvate dehydrogenase and a-ketoglutarate dehydrogenase because it makes a stable adduct with the groups of the dihydrolipoamide intermediate 4) Which of the following is NOT an electron acceptor in the mitochondrial respiratory chain? A) FMN B) FAD C) Fe3+ D) Cu2+ 8) Electron transport through NADH-Coenzyme ? reductase (Complex I) is accompanied by transfer of protons from the matrix to the intermembrane space 9) The Q cycle is responsible for transferring electrons from a two-electron donor one-electron acceptor chain. to a at the point of complex III of the mitochondrial respiratory

Explanation / Answer

1) A. Co-immunoprecipitation
10) dihydrolipoamide dehydrogenase
4) D. Cu2+
8) Four protons (4H+)
9) Cytochrome bc1 complex or CoQH2 to one electron acceptor ubiquinone
