You examine the structures of MET complexes I, II, III, and IV and discover that one of them is different from those found in human cells. Which complex is likely to be different? Explain. C. Do you expect to find cytochrome a3 in this novel MET system? Explain.Enzymes normally enhance the rates of biochemical reactions by preferentially binding and stabilizing the transition states rather than either the substrates or the products of a reaction. The F|-subunit of ATP synthase does not fit this norm so well as tight binding to ATP rather than a transition state is employed to make ATP. Explain the binding-change model of the mechanism of ATP-synthase. How and why is the proton-motive force used in the reaction cycle of ATP synthase?AG" = -69.5 kJ · mol- The percent efficiency of oxidative phosphorylation is 35%. Calculate the number of ATP generated by Complex I. Use 1 significant figure. The amount of ATP generated by Complex I is mol ATP.

Thanks A 45 year old man was rushed to the ER after ingesting "Galaxodin," a hypothetical poison. Explain why Galaxodin is toxic knowing that it increases the pH of the intermembrane space of mitochondria! You will need to give a comprehensive explanation of the process of energy conversion starting from NAH ending in ATP under normal conditions. Include details such as the transfer of electrons, the proton gradient, and chemiosmosis, NADH and FADH2, and ATP synthase must be mentioned. The majority of your grade will come from this part. Then explain why Galaxodin is so toxic!
