Quiz 70 / 1 ptsQuestion 1What change in thinking about oxidative phosphorylation occurred withacceptance of Peter Mitchel’s hypothesisacceptance of the idea that substrate level phosphorylation caused aproton gradient to formrealization that ATP production was causing a proton gradient that had tobe removed for further action of the ETCacceptance of the idea that a proton gradient powered the production of aphosphorylated intermediate used to make ATPthe idea that substrate level phosphorylation as the mechanism of ATPproduction was abandoned orrect Answer1 / 1 ptsQuestion 2What is the best description of the effects of an ATP synthase inhibitor likeoligomycin on isolated mitochondriaATP consumption starts, O2 consumption stops, and the proton gradient ishighATP production stops, O2 consumption stops, the proton gradient is high Correct!Correct!ATP production stops, O2 consumption continues, and proton gradient islowATP production stops, O2 consumption stops, the proton gradient is low 1 / 1 ptsQuestion 3When describing the energy contribution of NADH electrons made duringglycolysis when they are transported into the mitochondrion:electrons from the malate-aspartate shuttle enter complex I and electronsfrom the glycerol phosphate shuttle enter complex IIICorrect!Correct!electrons from the malate-aspartate shuttle enter complex III and theelectrons from the glycerol phosphate shuttle enter complex I electrons from either shuttle enter complex III electrons from either shuttle enter complex I 1 / 1 ptsQuestion 4What is the best description of the action of a transaminaseConverts one amino acid into another amino acid with the same carbonnumberConverts on amino acid into the corresponding alpha-keto acid, and adifferent alpha keto acid into the corresponding amino acidCorrect!Correct!Converts two distinct amino acids into their corresponding alpha-ketoacids, while generating the free amino groups to use in metabolismConverts alpha keto acids into amino acids, by transferring ammonia tothem0 / 1 ptsQuestion 5Which statement is trueB) glycolysis is exergonic and gluconeogenesis is endergonicThe exact reverse of the glycolytic reactions is endergonic, whilegluconeogenesis is exergonic orrect Answer only gluconeogenesis has reactions that consume ATP glycolysis is endergonic, and gluconeogenesis is exergonic Quiz Score: 3 out of
