Question
During the oxidative phosphorylation, Q cycle occurs in NADH dehydrogenase Succinate dehydrogenase Cytochrome bc_1 complex Cytochrome oxidase ATP synthase Which of the following statements about ATP synthase is not true? The F_1 domain contains 3 alpha, 3 beta and 1 of each gamma delta epsilon. The F_1 domain is responsible for proton transfer. F_0 rotate during ATP synthesis. ADP is converted to ATP on F_1 domain. Each beta subunit of F_1 domain has 3 different conformations. During the oxidative phosphorylation. O_2 is reduced to H_2O in Complex I Complex II Complex III Complex IV Complex V Which of the following statements about photosystems in plant is false? Both PSI and PSII absorb one photon per electron. NADPH is produced is PSI. PSI and PSII work in tandem. PSI absorbs light at shorter wavelength that PSII. Electrons are replaced by oxidation of H_2O to O_2. Which of the following molecules in an activator for PFK-1, but inhibitor for FBPase-1? ATP ADP F21, 6BP F1, 6BP CitrateExplanation / Answer
27. C - The reaction oxidative phosporylation catalyzed by cytochrome bc1 of the mitochondrial electron transport chain.
28. d is wrong. According to the current model of ATP synthesis (known as the alternating catalytic model), the transmembrane potential created by (H+) proton cations supplied by the electron transport chain, drives the (H+) proton cations from the intermembrane space through the membrane via the FO region of ATP synthase.
29. Cytochrome c oxidase (complex IV) reduce O2 to H2O (4cyt Cred + O2 + 8H+------->4cyt Coxd + 2H2O + 8H+)
30. D ; PS I absorbs light at 700 nm but PS II obsornds at 680 nm.
31. Fructose 2,6-bisphosphate or F2,6BP
