GLYCOLYSIS MCQ PDF

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. The respiratory quotient of an athlete running on a treadmill is found to be 0.

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.

A Iftheconcentrationsofthetwoproductsarehighrelativetothatoffructose1,6-bisphosphate. C Under standard conditions, enough energy is released to drive the reaction to the right. D Whenthereisahighconcentrationoffructose1,6-bisphosphaterelativetotheconcentrationof products.

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