One consequence of ethanol addiction is fatty liver disease, an illness in which liver cells accumulate large amounts of triacylglycerols, the esters derived from glycerol and fatty acids. Ethanol is oxidized in the cytoplasm of liver cells by alcohol dehydrogenase and aldehyde dehydrogenase to yield acetate and 2 NADH. Acetate is then transported into the mitochondrion, where it is converted to acetyl-CoA and metabolized in the citric acid cycle. When alcohol is consumed in excessive quantities, the resulting high levels of NADH cause metabolic abnormalities, one of which is high levels of fatty acid synthesis. Fatty acid synthesis, also a cytoplasmic process, uses acetyl-CoA as a substrate and NADPH as a reducing agent. Speculate about how a high level of cytoplasmic NADH provides a source of NADPH for fatty acid synthesis.
Of the 36 molecules of ATP produced by the complete metabolism of glucose, how many are produced directly in glycolysis alone, that is, before the common pathway?
How many total moles of ATP are created in a cell with an ATP synthase with 8 c subunits for every 28 moles of glucose that is completely oxidized in glycolysis and the Krebs cycle? Assume that NADH is transported by the malate aspartate shuttle.
Taking into consideration glycolysis, the pyruvate dehydrogenase complex and the citric acid cycle, how many NAD+ molecules are reduced from a single molecule of dihydroxyacetone phosphate? 4 NAD+ are reduced 5 NAD+ are reduced 8 NAD+ are reduced 10 NAD+ are reduced None of the above answers are correct
Assuming that the glycerol 3-phosphate shuttle is operative, a complete oxidation of five molecules of glucose (by a eukaryotic cell) into carbon dioxide and water would produce approximately _________ ATP molecules via oxidative phosphorylation only. (Consider NADH = 2.5 ATP and FADH2 = 1.5 ATP)
The citric acid cycle can be divided into two stages. In one stage, carbon atoms are added and removed, and in the second stage, oxaloacetate is regenerated. Which steps of the citric acid cycle correspond to each stage?
upon digestion of starch maltose, one of its degradation products is further hydrolyzed into its monosaccharide components prior to intestinal absorption and entry into the glycolysis. calculate the number of ATP molecules produced from the digestion and complete oxidation of 1 molecule of maltose considering the glycerol-3-phosphate shuttle. question: 5. what is the total number of acetyl CoA molecules entering the citric acid cycle
Which of the following is most likely to cause accumulation of acetyl CoA?

Which of the following is most likely to be true? Group of answer choices Fluoroacetate cannot be converted to fluoroacetyl CoA Fluoroacetyl CoA cannot be combined with oxaloacetate to enter the citric acid cycle Addition of fluoroacetate will cause an increase in isocitrate Aconitase cannot use fluorocitrate as a substrate
