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…

Hemp oil contains eicosenoic acid (20:149) as its primary monounsaturated fatty acid. Let's consider the conversion of a molecule of eicosenoic acid to B-hydroxybutyrate. 2022, 4. Arizona State University What are the f-oxidation products and how many ATP are required during activation for one molecule of lignoceric acid? Given the following, how many molecules of 6-hydroxybutyrate can be produced? COA OH COA NADH NAD+ B-hydroxybutyrate H* Based on the total NADH and FADH, available after converting lignoceric acid into ß hydroxybutyrate, what is the typical yield of ATP that can be produced in the liver? Don't forget to include any ATP required for activation steps.
