True FalseFill in the blanks using the following words/acronyms: protons; Electron Transport Chain; oxygen; inner; Cytochrome c; NADH; ATP synthase; shuttle; ATP (note: the same word/acronym may be used more than one time) Complex I transfers electrons from to Coenzyme Q; and this transfer leads to the extrusion of from the mitochondrial matrix to the outside face of the mitochondrial membrane. Complex II allows the transfer of electrons from succinate to Coenzyme Q. Coenzyme Q is an electron which transfers electrons to Complex III. Electrons transfer from Complex III is associated with translocation. These electrons are then accepted by ; which transfers them to Complex IV. are also translocated at the level of Complex IV during electrons transfer; allowing the reduction of the final electron acceptor of the which is . ll the translocated are then channeled through the pore of the ; providing the driving force for release from the Enzyme complex.What is the major route for protons moving from the inter membrane space back into the mitochondrial matrix during oxidative phosphorylation? 1.

- The image shows the flow of electrons through electron carriers I, II, III, and IV within the mitochondrial inner membrane. The electronegativity of the protein carriers determines their capacity to attract electrons. Based on the image, which of the following best describes the electronegativity of the carriers and the synthesis and utilization of ATP during the electron-transfer process? Electron carrier I is the least electronegative, and electron carrier IV is the most electronegative. ATP is required for electron transfer between carriers. Electron carrier I is the most electronegative, and electron carrier IV is the least electronegative. ATP is not required for electron transfer between carriers. Electron carrier I is the most electronegative, and electron carrier IV is the least electronegative. ATP is utilized in a distinct reaction, not directly coupled with electron transfer.
