Question

The glycerol-3-phosphate shuttle can transport cytosolic NADH equivalents into the mitochondrial matrix (see Fig. 15.11c). In this
shuttle, the protons and electrons are donated to FAD, which is reduced to FADH₂. These protons and electrons are subsequently
donated to coenzyme Q in the electron transport chain.
End of Chapter Problem 86a
How much ATP is generated per mole of glucose when the glycerol-3-phosphate shuttle is used?
(Tolerance is +/- 2%)
ATP are generated per glucose.

Transport of inorganic phosphate from the intermembrane space to the mitochondrial matrix affects the pH difference across the
inner mitochondrial membrane.
A phosphate ion enters the mitochondrial matrix in antiport with a proton (see Fig. 15.6b). This proton moves in
the same direction as the protons translocated by Complexes I, III, and IV. Thus, the difference in pH between the
mitochondrial matrix and the intermembrane space becomes smaller

In the first step of the citric acid cycle, an acetyl group from acetyl CoA reacts with oxaloacetate to form (a) pyruvate (b) citrate (c) NADH (d) ATP (e) CO2
Before pyruvate enters the citric acid cycle, it is decarboxylated, oxidized, and combined with coenzyme A, forming acetyl CoA, carbon dioxide, and one molecule of (a) NADH (b) FADH2 (c) ATP (d) ADP (e) C6H12O6
The oxidation of glucose to CO2 and water is a major source of energy in aerobic organisms. It is a reaction favored mainly by a large negative enthalpy change. C6H12O6(s) + 6O2(g) →6CO2(g) + 6H2O(l) ∆H° = -2816 kJ/mol ∆S ° = +181 J/mol . K (a) At 37 °C, what is the value for ∆G°? (b) In the overall reaction of aerobic metabolism of glucose, 32 moles of ATP are produced from ADP for every mole of glucose oxidized. Calculate the standard state free energy change for the overall reaction when glucose oxidation is coupled to the formation of ATP at 37 °C. (c) What is the efficiency of the process in terms of the percentage of the available free energy change captured in ATP?
In the 1930s, some physicians prescribed low doses of a compound called dinitrophenol (DNP) to help patients lose weight. This unsafe method was abandoned after some patients died. DNP uncouples the chemiosmotic machinery by making the lipid bilayer of the inner mitochondrial membrane leaky to H+. Chemical agents that cause this effect are called uncouplers. Explain how this could cause weight loss and also death. Considering the danger, is there any use for compounds like DNP or other uncouplers?
Pyruvate oxidizes to form carbon dioxide and water and liberates energy at the rate of 1142.2 kJ/mol. If electron transport also occurs, approximately 12.5 ATP molecules areproduced. The free energy of hydrolysis for ATP is 230.5kJ/mol. What is the apparent efficiency of ATP production?
Propose that you have discovered a new ATP synthase from the mitochondrion of an organism onthe planet X. You found that the mitochondrion from this newly discovered organism has exactly thesame electron transport chain as human beings. In addition, this newly discovered ATP synthase hassimilar subunit composition and arrangements as human beings, excepting that such newlydiscovered ATP synthase contain 6 c-subunits. Theoretically, the P/O ratio for the oxidation of FADH2 to water in this organism is: 1 1.5 2 2.5 3 3.5 None of the above Need more information Which statement is NOT true about the transport of ATP across the inner mitochondrial membraneon its way to the cytosol? The transport causes the loss of a net charge of -1 in the matrix. It is accomplished by adenine nucleotide translocase. The same enzyme that transports ATP also transport ADP in the opposite direction. It is complexed with Mg2+ to reduce the draw on the electrical part of the protonmotive force.
True or false 1. H+ ions generated by the reactions in the electron transport chain, as well as H+ ions present in the matrix of the mitochondria are pumped across the inner mitochondrial membrane into the intermembrane space at three different sites. 2. The electron transport chain is a multistep process that relies on five enzyme systems, as well as mobile electron carriers. 3. Energy released from H+ movement in the electron transport chain fuels phosphorylation. 4. The convertion of Fe3+ to Fe2+ in the electron chain is an example Fe3+ acting as an oxidizing agent. 5. The final stage of Electron Transport Chan is an anaerobic process.
a newly identified bacterium called Nomore biochem is unable to synthesize ubiquinone. A mobile electron carrier called CXC3 is used as a substitute.

(constants: R=8.3 J/degree x mol, F= 96.1 kJ/v x mol Half Reactions E' (V) ubiquinone + 2e- + 2H+--> Ubiquinol + H2 0.045 NAD+ + 2e- + 2H+ --> NADH + H+ -0.320 CXC3 + 2e- + 2H+ --> CXC3H2 -0.450 explain the impact that using CXC3 instead of ubiquinone will have on ATP production in the cell.
