- Remember that hexose kinase is an enzyme required for hexose metabolism, a process that takes a 6-carbon sugar and breaks it down into 2 pyruvate molecules. Practice Question 5 A) What is a specific metabolic process in which hexose metabolism occurs?arrow_forwardif each NADH generates 3 ATP molecules and each FADH2 generates 2 ATP molecules, calculate the number of ATP molecules generated from one saturated 10-carbon fatty acid Determine the number of repetitions of the β‑oxidation spiral needed to completely degrade the fatty acid to acetyl-SCoAacetyl-SCoA (acetyl-CoA)(acetyl-CoA) . Calculate the ATPATP produced by the acetyl-SCoAacetyl-SCoA molecules in the citric acid cycle. Calculate the ATPATP produced from the FADH2FADH2 and NADHNADH produced from β‑oxidation. Add the ATPATP generated (from step 2 and 3), and subtract the ATPATP needed to activate the fatty acid.arrow_forwardUnder aerobic conditions when glucose is limiting, with high ratios of NADH/NAD+ and ATP/ADP, as carbon-2 radiolabeled pyruvate is utilized for its carbon skeleton, which molecules would you expect to see significant radiolabeling in the liver? Select all that apply. (multiple answers) Glucose C-2 only Label is halved over many TCA cycles Oxaloacetate Glucose C-1 and C-6 Glucose C-2 and C-5 CO2 from TCA cycle shows some radiolabel Lactate C-2 for export Malate Pyruvate C-1arrow_forward
- Although both hexokinase and phosphofructokinase catalyze irreversible steps in glycolysis and the hexokinase-catalyzed step is first, phosphofructokinase is nonetheless the pacemaker of glycolysis. What does this information tell you about the fate of the glucose 6-phosphate formed by hexokinase? Glucose 6-phosphate must be unstable and release its phosphoryl group over time. Glucose 6-phosphate must be utilized by other metabolic pathways. Glucose 6-phosphate must allosterically inhibit phosphofructokinase, but not hexokinase. Glucose 6-phosphate must be wasted when it is produced in excess.arrow_forwardConsider 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.

- Table 9.2 shows that DGo’ for the aldolase reaction is large, and positive, yet the reaction proceeds in the forward direction. Using the metabolite concentrations in table 9.3, calculate the actual DG in the cell for the reaction to show that it is consistent with the value reported in table 9.2. Explain in words the strategy the cell uses to keep glycolysis moving in the forward direction (1-2 sentences).arrow_forwardConsider a 24:1 △cis-9 fatty acid in the mitochondrion.
