Solved in 2 steps
- 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.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.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")
- 36. In the conversion of pyruvate to acetyl CoA, - an acetyl group is transferred to Coenzyme A to produce acetyl CoA. - only one pyruvate molecule loses one carbon atom with the release of carbon dioxide. - the succinate dehydrogenase complex requires four coenzymes. - electrons are transferred to NADH to produce NAD*.Critically discuss the importance of the TCA cycle in carbohydrate metabolism. In your answer ensure you list the key reactions, clearly highlighting the metabolic intermediates, enzymes, enzyme complexes and hormones involved in the pathway and most importantly, how all of these intermediates are involved in the regulation of the pathway? Also emphasise how these intermediates themselves are regulated?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.
- Consider the complete oxidation of one mole of simple TAG containing behenic acid residues (22:0). II. What is the net ATP yield for the complete oxidation of all the fatty acid residues of the simple TAG? (Note: glycerol backbone is not included)Activity of Salivary Amylase: 1. Is there a difference in the time to dissolve the small and larger biscuit/cracker? Explain. 2. Explain your observations with the banana and egg.Account for the total no. of ATPs produced from β-oxidation for one mole of the given fatty acid (16C). How many acetyl-coA are formed?
- Fatty acid degradation stimulates the citric acid cyclethrough the activation of pyruvate carboxylase by acetylCoA. Why would the activation of pyruvate carboxylaseincrease energy generation from fatty acids?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??Please draw out mechanism The formation of fructose 1, 6- biphophste from dihydroxyacetome phospahte (DHAP) and Glyceraldehyde 3- phosphate (GAP) catalyzed by alsolase.
