Which of the following statements is TRUE regarding pyruvate oxidation? Question 12Select one: a. Pyruvate oxidation is an endergonic process, and does not produce any ATP or reduced electron carriers. b. Pyruvate travels from the mitochondria into the cytoplasm. c. The majority of the process of pyruvate oxidation takes place in the cytoplasm, with a small amount occuring in the mitochondria. d. With the initial input of 1 glucose molecule, pyruvate oxidation will release 2 molecules of carbon dioxide.

Which of the following statements about the energy yield of aerobic respiration is NOT true?A. Less than 50% of the chemical energy stored in glucose is converted to ATP.B. Glycolysis and pyruvate oxidation together provide more NADH per glucose molecule than doesthe Krebs cycle.C. Each pair of electrons donated by an FADH2 or NADH molecule during electron transport resultsin the synthesis of more than one molecule of ATP.D. ATP is needed to transport NADH produced during glycolysis into the mitochondria.E. Most of the ATP derived during aerobic respiration results from the utilization of anelectrochemical gradient.

Which of the following statements about the electron transport chain and ATP production in the mitochondria is false?Group of answer choicesAny drug that inhibits the ATP synthase will also inhibit the flow of electrons in the ETC.For oxidative phosphorylation to occur, it is essential to have a membrane that is impermeable to protons except through specific proteins pores or protein complexesThe yield of ATP per mole of fuel depends on the type of molecule being catabolized.Some complexes of the respiratory chain pump protons into the matrix to create an electrochemical gradient.Exergonic electron transfer provides the energy for proton pumping.

Which of these biochemical processes would you expect to liberate the most ATP?a) Gluconeogenesisb) Fatty acid synthesisc) Glycolysisd) Beta oxidatione) Electron transport chain activity

Which statement about the production of pyruvate in the final step of glycolysis is CORRECT? A. Pyruvate kinase transfers a phosphate group from ATP to PEP to generate pyruvate and ADP. B. The unfavourable conversion of PEP to pyruvate is driven largely by the highly favourable standard free energy change for the hydrolysis of ATP to ADP. C. The standard free energy change for the conversion of PEP to pyruvate is very highly favourable to counteract the unfavourable phosphorylation of ADP to ATP.
