Use your answers from parts B and C to calculate the total number of ATPs generated from the metabolism of a saturated fatty acid with 18 carbon atoms including both the citric acid cycle and the ββbeta-oxidation pathway as well as the initial ATP required to produce the acyl-SCoA molecule that starts the process.

- This is the ATP accounting question. You are limited to the carbon in the following molecules: One xylulose 5-phosphate, One glyceraldehyde 3-phosphate, One sedoheptulose 7-phosphate, 1 Oxaloacetate, and 3 carbon dioxide A) Disregard regulation completely regarding pathway activity, using only the enzymes of glycolysis, pentose phosphate pathway, and citric acid cycle, what is the maximum ATP one can generate with these molecules? B) Disregard regulation completely regarding pathway activity, using only the enzymes of glycolysis, Calvin- Benson-Bassham cycle, and citric acid cycle, what is the maximum ATP one can generate with these molecules (in this instance only, you also are given 3 ATP and note that you do NOT need to regenerate substrates for rubisco once you get through this enzyme).arrow_forwardATP is an ALLOSTERIC INHIBITOR of the phosphofructokinase enzyme, which is a key catalyst for one of the first steps of Glycolysis. Citrate (citric acid) is a 6-carbon product of the first reaction of the Krebs Cycle (aka Citric Acid Cycle). Interestingly, Citrate enhances the inhibitory effect of ATP on phosphofructokinase. What is a likely explanation for the inhibitory effects of these molecules? Excess ATP and Citrate signal the cell that Glycolysis should be speeded up. Excess ATP and Citrate signal a positive feedback loop. Excess ATP and Citrate signal the cell that Glycolysis should be slowed. Excess ATP and Citrate compete for the active site of phosphofructokinase.arrow_forwardCompare and contrast Pyruvate Dehydrogenase with a-ketoglutarate dehydrogenaseOutline the mechanisms of both enzymes.
