During anaerobic exercise, the Cori cycle connects which two metabolic pathways?A.Glycogenolysis and the citric acid cycleB.The urea cycle and gluconeogenesisC.The pentose phosphate pathway and glycogenesisD.Gluconeogenesis and glycolysis

The Krebs cycle: A) Uses glucose B) Is part of anaerobic glycolysis C) Is part of aerobic glycolysis D) Consumes ATP and produces CO2 E) Produces GTP, NADH, and CO2

Which statement best describes how the citric acid cycle relates to glycolysis, oxidative phosphorylation, and chemiosmosis?A. Glycolysis produces pyruvate, which directly enters the citric acid cycle. This cycle produces the energy currency that undergoes the electron transport chain to produce water and ATP.B. The citric acid produces pyruvate, which converts to glucose to enter glycolysis. This pathway produces NADH and FADH2, which enter oxidative phosphorylation to produce ATP through chemiosmosis.C. Glycolysis produces pyruvate, which is converted to acetyl-CoA and enters the citric acid cycle. This cycle produces NADH and FADH2, which donate electrons to the electron transport chain to pump protons and produce ATP through chemiosmosis. Production of ATP using an electron transport chain and chemiosmosis is called oxidative phosphorylation.D. Citric acid produces NADH and FADH2, which undergo oxidative phosphorylation. This produces ATP by pumping protons through chemiosmosis. The ATP produced is utilized in large amounts in the process of glycolysis.

What evidence provides the strongest support that glycolysis is an older and more conserved pathway than the citric acid cycle?A. The pathway only occurs in the mitochondria. It is highly flexible because it is found in almost all organisms.B. The pathway occurs in the cytosol, is found in all animals and plants, and does not require oxygen.C. Glycolysis is the primitive pathway, found in all three domains. It also occurs in anaerobic conditions and in the cytosol.D. Glycolysis takes place in anaerobic conditions, can metabolize cholesterol and fatty acids, and occurs even in methanogens.
