- a- During intense exercise the transformation glucose to lactate causes very less ATP production compared to aerobic glycolysis. Explain, does anaerobic glycolysis lead to waste of energy in muscle? b-Glycogen phosphorylase enzyme catalyzes the removal of glucose from glycogen. Describe, glycogen metabolism regulation through glycogen phosphorylase.arrow_forwardc) Cooperation between glycolysis and gluconeogenesis is important to ensure the glucose-subjected energy demands of specific cells are met. Explain this statement.arrow_forwardA number of genetic deficiencies in acyl CoA dehydrogenases have been described. This deficiency presents early in life after a period of fasting. Symptoms include vomiting, lethargy, and sometimes coma. Not only are blood levels of glucose low ( hypoglycemia), but starvation-induced ketosis is absent. Provide a biochemical explanation for these last two observations.arrow_forward
- A. Provide a reasonable mechanism for the production of geranyl pyrophosphate from IPP andDMAPPB. How many molecules of IPP and how many molecules of DMAPP would you need to makefarnesyl pyrophosphatearrow_forwardHow Is Metabolism Regulated? (Integrates with Chapter 15.) Metabolic regulation is achieved via regulating enzyme activity in three prominent ways: allosteric regulation, covalent modification, and enzyme synthesis and degradation. Which of the.se three modes of regulation is likely to be the quickest; which the .slowest? For each of these general enzyme regulatory mechanisms, cite conditions in which cells might employ that mode in preference to either of the other two.arrow_forwardModeling 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.arrow_forward
- Understanding the Oxidation of Glucose and Its Products in the TCA Cycle Glycolysis, the pyruvate dehydrogenase reaction, and the TCA cycle result in complete oxidation of a molecule of glucose to CO2. Review the calculation of oxidation numbers for individual atoms in any molecule, and then calculate the oxidation numbers of the carbons of glucose, pyruvate, the acetyl carbons of acetyl-CoA. and the metabolites of the TCA cycle to convince yourself that complete oxidation of glucose involves removal of 24 electrons and that each acetyl-CoA through the TCA cycle gives up 8 electrons.arrow_forwardRegulation of Glutamine Synthetase by Covalent Modification Suppose at certain specific metabolite concentrations in vivo the cyclic cascade regulating E. coli glutamine synthetase has reached a dynamic equilibrium where the average state of GS adenylylation is poised atn=6.
