Aerobic respiration differs from anaerobic respiration in which aspect? The presence of oxygen as the final electron acceptor in aerobic respiration O The production of lactic acid or ethanol as byproducts in aerobic respiration. The use of glycolysis as the initial step in glucose metabolism only occurs in aerobic respiration Only aerobic respiration generates ATP
The complete aerobic respiration of glucose yields far more energy stored in ATP than glycolysis alone for all of the following reasons EXCEPT: Krebs cycle generates reduced electron carrier molecules (NADH and FADH2) Krebs cycle generates some additional ATP through substrate-level phosphorylation Glycolysis only partially oxidizes the glucose molecule to pyruvic acid None of the other four answers (all are reasons that aerobic respiration yields more energy than glycolysis alone) Electron transport chain (terminal respiratory pathway) produces many ATPs through oxidative phosphorylation using electron carrier molecules (NADH and FADH2)

In biological systems, anabolic and catabolic reactions are "coupled" (or linked) by: Krebs cycle The Electron Transport Chain Photosynthesis Adenosine Triphosphate (ATP) Glycolysis
Which of the following compounds involved in aerobic respiration can originate from the breakdown of proteins? Select all that apply. Citric acid cycle intermediates Acetyl-CoA Pyruvate PGAL
The energetically-usable products of aerobic respiration are: O A diverse number of protein molecules O Up to 38 ATPS O Three unsaturated fatty acids O Six carbon dioxide molecules O Glucose molecules (the number depends on the amount of light available)
Which of the following are true statements regarding cellular respiration? (Select all that apply) Group of answer choices Lactic acid fermentation is an aerobic process The final electron acceptor in the electron transport chain is oxygen Two ATP are produced in the citric acid cycle Glycolysis produces two net molecules of ATP Four ATP are produced in the Krebs cycle
Which of the following statements best explains why anaerobic respiration releases energy from organic compounds Anaerobic respiration partially oxidizes glucose, which is an organic compound This happens during glycolysis The result of the glycolysis is the net production of 2 ATP molecules which are used by the cell for energy Anaerobic respiration partially oxidizes glucose, which is an inorganic compound This happens during glycolysis The result of the glycolysis is the net production of 4 ATP molecules which are used by the cell for energy Anaerobic respiration partially oxidizes glucose, which is an organic compound This happens during glycolysis The result of the glycolysis is the net production of 4 ATP molecules which are used by the cell for energy Anaerobic respiration fully oxidizes glucose, which is an organic compound This happens during glycolysis The result of the glycolysis is the net production of 4 ATP molecules which are used by the cell for energy
Which stage of aerobic respiration requires an input of oxygen? Acetyl-CoA formation Citric acid cycle Glycolysis Electron transfer phosphorylation
The complete catabolism of glucose into CO2 and H2O generally yields a smaller amount of ATP in aerobic eukaryotes than in aerobic prokaryotes because the aerobic eukaryotes: generate more molecules of FADH2 during aerobic respiration have transport costs to get NADH into the mitochondrion generate more molecules of NADH during aerobic respiration are able to use pyruvate as a substrate for fermentation always produce ethanol rather than lactic acid as a byproduct
All of the following are true for both anaerobic respiration and fermentation except: Lack the electron transport chain Result in the production of NADH Produce less ATP than aerobic respiration Involve the breakdown of glucose to pyruvic acid Can proceed in the absence of oxygen
Aerobic respiration in eukaryotes produces less ATP per glucose molecule than aerobic respiration in prokaryotes. This is because: the electrons from cytoplasmic NADH in eukaryotes are shuttled to ubiquinone instead of NADH dehydrogenase. prokaryotes can produce a larger proton gradient across the inner mitochondrial membrane, thus causing a greater driving force for ATP synthesis. fermentation and the tricarboxylic acid cycle can run simultaneously in prokaryotes, generating two additional ATP per glucose molecule. eukaryotes must actively transport glucose into the mitochondria where respiration А. B. C. D. occurs. prokaryotes can generate 2.5 ATP per FADH2 molecule, whereas eukaryotes can only generate 1.5 per FADH2 Е. E.
