A major pathway for metabolism of ethanol is shown below. Humans consuming a large fraction of their calories in the form of ethanol may become hypoglycemic. This is because: Ethanol is a good solvent, and it dissolves the membranes of the mitochondria, where some of the gluconeogenic enzymes reside.   b. Ethanol metabolism indirectly inhibits pyruvate kinase, by consuming NAD.     d. Ethanol metabolism indirectly inhibits lactate dehydrogenase, by consuming NAD.     f. The assertion in the question is incorrect, because acetyl-CoA can be used for synthesis of glucose.   g. Ethanol metabolism indirectly inhibits pyruvate carboxylase, by consuming NAD.   h. Ethanol metabolism indirectly inhibits phosphoenolpyruvate carboxykinase, by consuming NAD.
