Solved in 3 steps
- All the dehydrogenases of glycolysis and the citric acid cycle use NAD+ (?′°E′° for NAD+/NADH is −0.32 V−0.32 V) as electron acceptor except succinate dehydrogenase, which uses covalently‑bound FAD (?′°E′° for FAD/FADH2 in this enzyme is 0.050 V).0.050 V). The ?′°E′° value for fumarate/succinate is 0.031 V.0.031 V. a)Calculate the Δ?′°ΔG′° value for the oxidation of succinate using NAD+. b)Calculate the Δ?′°ΔG′° value for the oxidation of succinate using covalently‑bound FAD.How many ATP molecules can be synthesized from four Acetyl CoA molecules if all four enter the Kreb's Cycle? Assume the energy yielding products enters the ETC.Calculate production of NADH, FADH, and GTP molecul in complete oxidation often molecules of glucose by citric acid cycle
- Why does FAHD2 oxidation give 1.5 ATP while NADH oxidation gives 2.5 ATP? Explain this in relation to ETC.From the complete oxidation of glucose (glucose > 6CO2), how may total NADH electron carriers are produced?Explain in ( Claim , Evidence ,reason ) An electron carrier is added to mitochondria that will take electrons from NADH, and pass them directly on to CoQ. What will be the effect on flux through the ETC? In particular, describe the impact on e- movement AS WELL AS H+ movement through the ETC complexes.
- Which step(s) of cellular respiration would be directly inhibited by high concentrations of NADH? How would this affect other steps of cellular respiration?ndicate whether each of the following statements is true or false. If false, correct the statement or provide a briefexplanation for why it is false.g. The high potential electrons of NADH enter the respiratory chain at NADH-Q reductase.h. Ubiquinol (QH2) is also the entry point for electrons from NADH of flavoproteins.i. Cytochrome reductase catalyzes the transfer of electrons from cytochrome c to O2.true or false NADH and FADH2 deliver the same number of electrons to the ETC?
- What is the P:O ratio for electrons entering the electron-transport chain that originate from reoxidation of acyl-CoA dehydrogenase? A. greater than the P:O ratio for NADH reoxidation B. approximately the same as the P:O ratio for NADH reoxidation C. less than the P:O ratio for NADH reoxidation but more than the P:O ratio for Complex II reoxidation D. approximately the same as the P:O ratio for Complex II reoxidation E. less than the P:O ratio for Complex II reoxidationChoose the correct answer from the options in brackets. The [positive/negative] standard free‑energy change favors the oxidation of succinate by covalently‑bound FAD. This is consistent with K′eq [ >1 / =1 / <1 ]. Oxidation by NAD+ would require a large, [positive/negative] standard free‑energy change, with K′eq favoring the synthesis of succinate.When 12 molecules of glucose enter glycolytic pathway, how much NADH molecules are prdouced?
