No, because NAD* will not be regenerated by lactate dehydrogenase. The reduction of NAD+ to NADH is a required step during the payoff phase of glycolysis. O b. No, because lactate dehydrogenase is required for the continued recycling of NAD+ to NADH, thus allowing glycolysis to continue. Oc. Yes, because pyruvate dehydrogenase is necessary to produce acetyl-CoA, which under these conditions will feed into the citric acid cycle. Od. Yes, because this enzyme is responsible for the substrate-level phosphorylation necessary to maintain the ATP input for the preparatory phase of glycolysis.

- When muscles contract, a chain of events result in greater activity by the TCA cycle. All of the following are links in that chain EXCEPT: The ADP concentration increases. Rate of respiration and oxygen consumption increases. The electron transport chain produces more water. The concentration of NADH decreases and the concentration of NAD+ increases. 2) (True or False )______The concentration of oxaloacetate drops and TCA cycle is halted which leads to the synthesis of ketone bodies. 3) NADPH is used for: a) Oxidizing vitamin E b) Oxidizing glutathione c) Reductive biosynthesis of fatty acids d) β-oxidation of fatty acidsarrow_forwardA decrease in transport system. would be LEAST likely to affect the processes of the electron Ooxygen concentrations in the cell O the concentration of cellular NADH O cellular CO₂ concentrations O the TCA cycle activityarrow_forwardWhich of the following is true for both aerobic and anaerobic cellular respiration?

- Which of the following statements is false concerning the ‘tight binding site’ of ATP Synthase within the natural environment of the mitochondria? Group of answer choices ATP is released from the tight binding site This is a binding site found within an αβ subunits of the F1 portion of ATP Synthase The tight binding forces the reaction of ADP + Pi → ATP The tight binding site has the lowest KM for ATParrow_forward1 mole of glucose gives rise to a net ATP production of and the TCA cycle. Assume 1 NADH gives rise to 3 ATP and 1 FADH2 gives rise to 2 ATP. O 20 moles of ATP O 15 molecules of ATP O2 moles of ATP O 4 moles of ATP O 10 molecules of ATP 38 moles of ATP O 10 moles of ATP O 15 moles of ATP O 38 molecules of ATP after glycolysisarrow_forwardChoose any/all that apply to the proton-motive force and ATP synthesis. The active pumping of protons through ATP synthase against their concentration gradient provides the energy needed for ATP synthesis. Rotation of the y subunit creates conformational changes in the active sites of ATP synthase that drive the release of ATP from the enzyme. Each 3 subunit of ATP synthase has a distinct amino acid sequence that accounts for the three different active sites present in the enzyme. The ATP molecules produced from the pair of electrons provided by NADH have greater potential energy than the ATP molecules produced from the pair of electrons provided by FADH₂. Inhibition of either ATP synthase or ATP translocase will stop flux through the electron- transport chain.arrow_forward
