- Effects of Changing Metabolite Concentrations on Glycolysis In an erythrocyte undergoing glycolysis what would be the effect of a sudden increase in the concentration of a. AΤP? b. AMP? c. fructose-1.6-bisphosphate? d. fructose-2, 6-bisphosphate? e. citrate? f. glucose-6-phospthate?Modeling the Regulation of AcetyI-CoA Carboxylase Based on the information presented in the text and in Figures 24.4 and 24.5, suggest a model for the regulation of acetyl-CoA carboxylase. Consider the possible roles of subunit interactions, phosphorylation, and conformation changes in your model.9Calculate the total amount of ATP that is produced by the complete oxidation of a 20 carbon even-chain saturated fatty acid. Include the number of each cycle required, describe each stage involved, and list the number of ATP that correspond with each stage.
- Considering the fatty acids: (a) Arachidic acid (C20H40O2); molar mass = 312.5 g/mol) (b) Palmitoleic acid (C16H30O2); molar mass = 256.4 g/mol). How many cycles of β -oxidation are needed for complete oxidation? How many molecules of acetyl CoA are formed from its complete catabolism? How can you calculate the number of molecules (moles) of ATP formed (net) by the complete catabolism of each fatty acid? and the number of moles of ATP formed per gram of each fatty acid metabolized??Which fatty acid cannot undergo β-oxidation in principle, why? Write all the β-oxidation steps for the fatty acid that can undergo β-oxidation, including the cofactors and products.Insulin-dependent diabetes is often accompanied by hypertriglyceridemia, which is an excess blood level of triacylglycerols in the form of very low density lipoproteins. Suggest a biochemical explanation.
- ATP yield. Each of the following molecules is processed by glycolysis to lactate. How much ATP is generated from each molecule?Pls help ASAP, thank you! "Match the gluconeogenic precursor to the type of reaction(s) that bring it to gluconeogenesis as pyruvate" (answer choices for all drop down menus are: "alanine", "lactate", "glycerol", and "glutamine")One metabolic scenario that leads to insulin resistance is the elevation of the conccentration of free fatty acids in skeletal muscle cells. Would you expect increased activity of diacylglycerol acyltransferas (DGAT) to reduce or exacerbate the resistance? Explain.
- Efficiency of ATP Production in Muscle: The transformation of glucose to lactate in myocytes releases only about 7% of the free energy released when glucose is completely oxidized to CO2 and H2O. Does this mean that anaerobic glycolysis in muscle is a wasteful use of glucose? Explain.Calculate the net ATP yield from the complete processing of a saturated fatty acid containing 17 carbons. Consider the β-oxidation steps, processing of acetyl-CoA through the citric acid cycle, and electron transport.Predict which one of the five steps of the α-ketoglutarate dehydrogenase complex reaction is metabolically irreversible under physiological conditions and explain why.
