6-phosphate, 1.0 mM; fructose-1,6-bisphosphate, 10 mM; AMP, 0.1
mM; ADP, 0.5 mM; ATP, 5 mM; and P;, 10 mM. Is the phosphofruc-

Answer: glycogen, direct phosphorylation, glycolysis, cellular respiration Is this the answer??arrow_forwardChapter: Lipid Metabolism Individuals with abnormally low levels of carnitine in their muscles suffer from muscular weakness during moderate exercise. In addition, their muscles have significantly increased levels of triacylglycerols. (a) Explain these two effects. (b) Can these individuals metabolize muscle glycogen aerobically?arrow_forwardMuscle protein, fat, and glycogen are all reservoirs of energy. In what order are they used during a prolonged fast?arrow_forward

(Hint: Review Figure 5.3.) Q3: Arsenic disrupts ATP production. Why would this characteristic cause it to be a potent poison?arrow_forwardQ2. It has been estimated that two high-energy phosphate bonds must be expended to incorporate one glucose molecule into glycogen. Why is glucose stored in muscle and liver in the form of glycogen, and not as individual glucose molecules? In other words, why is it advantageous for a cell to expend metabolic energy to polymerize glucose molecules?arrow_forward
- Does biochemistry involve nutrition? If so, which loading method, either carbohydrate or lipid, would be the best to utilize pre- and during aerobic performance? And how can carbohydrate or lipid loading negatively impact aerobic performance?arrow_forwardIf fatty acids are a more efficient storehouse of energy than glucose or glycogen, why aren't they used immediately to drive muscle contraction?arrow_forward. Liver is primarily a gluconeogenic tissue, whereas muscle is primarily glycolytic. Why does this division of labor makegood physiological sense?arrow_forward
