Electron transport chain Krebs cycle Conversion of pyruvate into acetyl CoA Glycolysisarrow_forwardLiver cells need NADH and ATP for gluconeogenesis, which involves both cytoplasm and mitochondria. From cytoplasm, pyruvate enters the mitochondria via transporter protein and in mitochondria, pyruvate undergoes carboxylation and reduction.

- 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)arrow_forwardIn which stage of aerobic cellular respiration are FADH2 molecules produced? Pyruvate Oxidation Glycolysis Krebs Cycle Electron Transportarrow_forwardKrebs (citric acid) cycle and electron transport chain belong to: glycolysis aerobic (cell) respiration anaerobic fermentation lactic fermentationarrow_forward
- ATP synthesis in mitochondria requires all of the following EXCEPT (select two answers) a hydrogen ion concentration gradient across the inner mitochondrial membrane the oxidation of dinucleotide molecules that act as electron carriers fermentation of pyruvate into lactate to regenerate NAD+ the reduction O2, forming H2O the breakdown of glucosearrow_forwardAerobic 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.
