Question
BIOCHEMISTRY MC 6) Moblle Electron carriers of the mitochondrial ETC are: (only on answer is correct) A. Cytochrome C incorrect B. Coenzyme Q incorrect C. Both of the above D. None of the above MC 7) In the absence of water (and equal presence of all other reactants/products) the free energy change of ADP phosphorylation is: (only one answer is correct) A. Highly negative B. Highly positive C slighly negative D: None of the above MC 8) Forms of free energy can be: (only one answer is correct) A. The imbalace of a chemical species across a biomembranne B. A membrane potential difference C. Both of the above D: None of the above MC 9) If the proton concentration in the mitochondrial intermembrane space is lower than in the matrix and that of ATP in the matrix is very high... (only one answer is correct) A. The FATPase hydrolyzes ATP B. The F-ATPase pumps protons into the intermembrane space C. Both of the above D: None of the above MC 10) Which of the following protein complexes can pump protons in normally operating mitochondria? (only one answer is correct) A. NADH-Q oxidoreductase B. Cytochrome C oxidase C. Both of the above D. None of the aboveExplanation / Answer
6 Both Cytochrome C and Co enzyme Q transport electrons in ETC hence optionC is correct.
7.Free energy change is positive as for phosphorylation one additional Pi is attached to ADP jence option B is correct.
8. Free energy can be released as chemical imbalance or membrane potentipo difference or electrochemical gradient. Option C is correct.
9. (None of the above) because when hydrogen pass through F1 ATPase ATPs are generated.
10.Both ubiquinone and Cytochrome-c-oxidase can pump proton in intermembrane space to generate proton gradient. Hence opopti C is correct.
