Which enzyme is used for both the synthesis and breakdown of acetoacetate? thiolase O HMG-CoA synthase OB-hydroxybutyrate dehydrogenase O B-Ketoacyl-CoA transferase
Strategies for regulating the central pathways in carbohydrate metabolism vary among different cells in one organism and among organisms. Slight changes in the regulation of enzymes in central metabolism can effectively re-route metabolite traffic through these pathways, just like a small mutation in PFK-1 can convert a healthy cell into a cancerous one. For instance, Gillaspera mold uses an alternative strategy for regulation the TCA and glycolysis. Gillaspera contains a unique isocitrate dehydrogenase that has an allosteric site for citrate. High citrate inhibits isocitrate dehydrogenase in this organism. Gillaspera also lacks a citrate binding site on PFK-1, so this variant of the enzyme is not affected by citrate concentrations at all. Gillaspera lacks the enzymes ethanol dehydrogenase and lactate dehydrogenase and no carbons are lost in its unique fermentation product. Would high glucose in these organisms lead to production of carbon dioxide from glucose catabolism?…
The respiratory quotient (RQ) is the ratio of the Liters of CO2 produced to the Liters of O2 consumed by an individual (CO2 exhaled in liters)/(O2 inhaled in liters). It is used as a measure of basal metabolic rate and can indicate which types of molecules are being used by a person to produce energy. For glucose (C6H12O6), this value is 1 as the equation for the complete oxidation of glucose is: C6H12O6 + 6 O2 → 6 CO2 + 6 H2O For fatty acids that are degraded through beta oxidation and fed into the TCA cycle, the RQ value would be ______ the values for glucose oxidation. Fill in the blank with: a) higher than b) the same as c) lower than
choose the metabolic pathway being described in the statement choices: Digestion Glycolysis Formation of Acetyl CoA Krebs Cycle ETC Reactions Glycogenesis Glycogenolysis Gluconeogenesis 1. catalyzed initially by glycogen phosphorylase 2. breaking of glycosidic linkages of glycogen 3. requires pumping of hydrogen ions 4. lactic acid is converted to glucose
A patient who has been drinking large amounts of alcohol for long periods of time shows thefollowing symptoms: apathy, loss of memory, and a rhythmical to-and-fro motion of the eyeballs.Which of the following reactions are most likely to be affected in the patient? A. Conversation of pyruvate to acetyl-CoA B. Conversation of a-ketoglutarate to succinyl-CoA C. Both A and B D. Neither A nor B
State the steps of ketone body formation, starting with two acetyl CoA. Please make sure to state all the enzymes and co-factors for each reaction.
Consider fatty acids from the hydrolysis of the given TAG in a liver cell where amino acid and nucleotide biosynthesis is very active For each fatty acid given, determine the following. Gross ATP from b-oxidation cycles Gross ATP from acetyl CoA produced Gross ATP from conversion of propionyl CoA (if applicable) Total number of ATP deducted Total net ATP
Please explain
Under aerobic conditions of high ratios of NADH/NAD+ and ATP/ADP, as pyruvate is utilized for its carbon skeleton, which molecules would you expect to see significant radiolabeling in the liver? Select all that apply. **Please note some molecules contain more details, including not only molecule name, but location of the label. Pick the options that are accurate for the above situation. Glucose C-2 and C-5 Glucose C-1 and C-6 Glucose C-2 only Pyruvate C-1 Lactate C-2 for export CO, from TCA cycle shows some radiolabel Label is halved over many TCA cycles Oxaloacetate Malate
Deficiencies in the conversion of Pyruvate to Acetyl CoA may result in severe neurological developmental defects in children. A child presents with these symptoms. Tests reveal that this child has abnormally high levels of Pyruvate in mitochondria and low levels of Hydroxyethyl TPP. What is your diagnosis on the specific enzyme deficiency in this child that may be causing the symptoms Explain in 3 – 5 sentences
Fill in the blanks below (input numbers only!) about the metabolism of hexanoic acid, a fatty acid that is one of the components of vanilla, and whose formula is CH3(CH2)4COOH: First, the fatty acid is activated by attaching CoA, which costs ATP molecules. The fatty acid is then broken down through a beta-oxidation spiral, to make acetyl CoA molecules. This will require "turns" of the beta-oxidation process. Since each turn of the cycle yields ATP molecules, and each acetyl COA will yield ATP molecules by going through the rest of its metabolism, the net ATP molecules produced from one molecule of this fatty acid will be
