Oxidative Phosphorylation (Ch. 19) 1. The NADH dehydrogenase complex of the mitochondrial respiratory chain promotes the following series of oxidation-reduction reactions, in which Fe* and Fe2* represent the iron in iron-sulfur centers, Q is ubiquinone, QH2 is ubiquinol, and E is the enzyme: (1) NADH + H* + E-FMN → NAD* + E-FMNH2 (2) E-FMNH2 + 2Fe³+ (3) 2FE2+ + 2H* + Q· → E-FMN + 2Fe²+ + 2H+ 2Fe3+ + QH2 Sum: NADH + H* + Q–→ NAD* + QH2 For each of the three reactions catalyzed by the NADH dehydrogenase complex, identify (a) the electron donor, (b) the electron acceptor, (c) the conjugate redox pair, (d) the reducing agent, and (e) the oxidizing agent.

Many metabolites are transported either actively or passively across mitochondrial outerand inner membrane, like metabolites involved in urea cycle.(A) Besides the metabolites involved in urea cycle, name other metabolites that aretransported across the mitochondrial membranes and explain the biological importancefor transporting those metabolites (B) Mice fed with amphipathic chemical W, K and V were found to lose body weight. It wassuspected that W and K affected mitochondrial functions. The amount of foodconsumed by the mice was consistent throughout the experiment.i. When mice were fed with W, all mitochondrial proteins were function properly. Howdid W induce body weight loss? ii. When mice were fed with K, less complex III and IV were reduced in the electrontransport chains. Other mitochondrial proteins were function properly. How did Kinduce body weight loss? iii. When mice were fed with V, adenosine monophosphates (AMPs) were accumulated incytosol and mitochondria while no…
From the complete oxidation of glucose (glucose → 6CO2), how many total NADH electron carriers are produced?
If α-ketoglutarate is removed from TCA cycle and used to make glutamate, how many of each of the cofactors (not intermediates) and high energy molecules in the TCA cycle are lost? How much ATP does this equate to (NADH = 2.5 ATP, FADH2 = 1.5 ATP)?
