Erythrocytes red blood cells have no mitochondria, and thus cannot use oxidative phosphorylation to produce additional ATP from pyruvate derived from glycolysis. Liver cells hepatocytes , neurons, and muscle cells myocytes can derive some ATP from glycolysis, but then feed the resulting pyruvate into the Krebs cycle in the mitochondria for additional energy production. Which of the following biological processes will occur under both aerobic and anaerobic conditions in humans? The correct answer is glycolysis.

Who Is It For? Glycolysis is the name given to a metabolic pathway occurring in many different cell types. It consists of 11 enzymatic steps that convert glucose to lactic acid.
Glycolysis is an example of: A aerobicmetabolism. B anabolic metabolism. C a net reductive process. D fermentation. E oxidative phosphorylation. Which of the following statements is not true concerning glycolysis in anaerobic muscle? A Fructose1,6-bisphosphataseisoneoftheenzymesofthepathway. B It is an endergonic process. C It results in net synthesis of ATP. It is an endergonic process. When a muscle is stimulated to contract aerobically, less lactic acid is formed than when it contracts anaerobically because: A glycolysisdoesnotoccurtosignificantextentunderaerobicconditions.
B muscle is metabolically less active under aerobic than anaerobic conditions. C the lactic acid generated is rapidly incorporated into lipids under aerobic conditions. D underaerobicconditionsinmuscle,themajorenergy-yieldingpathwayisthepentosephosphate pathway, which does not produce lactate. E under aerobic conditions most of the pyruvate generated as a result of glycolysis is oxidized by the citric acid cycle rather than reduced to lactate.
Glycolysis in the erythrocyte produces pyruvate that is further metabolized to: A CO2. B ethanol. C glucose. D hemoglobin. E lactate. When a mixture of glucose 6-phosphate and fructose 6-phosphate is incubated with the enzyme phosphohexose isomerase, the final mixture contains twice as much glucose 6-phosphate as fructose 6-phosphate.

E When there is a high concentration of products relative to the concentration of fructose 1,6- bisphosphate.

Following the depletion of muscle phosphocreatine stores through intense sprint exercise, which is true of the time course for complete re-synthesis of these stores? Muscle cannot release its stored glycogen into the circulation to maintain blood glucose levels because it lacks the enzyme:. Before the pyruvate that has been generated by glycolysis can be oxidized, it must be transported into a mitochondrion. This is accomplished by:. Which is true regarding the efficiency of the oxidation of fat vs.
