P. Emer Shift 1O. An essential feature of the glyoxylate eyele, which is not associated with the TCA cycle is: (3 a. it utilizes condensation of acetyl-CoA with glyoxylate b. each complete cycle produces a net gain of two 4-carbon molecules it occurs in clhloroplasts and the mitochondria of plant seeds d. mammals use the glyoxylate cycle for gluconeogenesis e it is a reductive pathway that utilizes NADPH as an electron source 10. Complex I contains all of these components EXCEPT: Gpts) a. [FMN]. b. 2Fe-28 clusters. c. 4Fe-4S clusters d. cytochrome c. e "proton pump." 11. The first half of the Q cycle results in which of the following? (3pts) a transfer of 4 protons to the intermembrane space b. a semiquinone radical (UQ) in the On site c. 2 molecules of reduced cytochromec d. return of one UQlH2 to the coenzyme Q pool e, none of the above 12. All of the following take place in the Q cyele EXCEPT: (3pts) a. transfer of electrons from bu to by b an electron is passed from by to UQ. C. an electron is passed from bu to UG. d. one UOtz is returned to the pool. e. two protons are pumped into the matrix. 13. Complex III takes upproton(s) on the matrix side of themembrane and releases_ protons on the intermembrane side for each pair ofpassed through the Q eycle.(3pts) a. two; inner; four; electrons b. one; inner; two; protons c. two; inner; four; protons d. one; outer, two; electrons e. none are trueExplanation / Answer
