HN 308 final pt. 2 Questions with Complete Solutions

b-oxidation needs mitochondria, sends FA (aceyl-CoA) to mitochondria via carnitine - b-oxidation occurs and acetyl-CoA occurs - acetyl-CoA cannot convert to pyruvate so cannot engage in gluconeogenesis Correct Answer-so why cant acetyl-coa derived from beta oxidation be used to convert into glucose? beta-oxidation, then can enter TCA (acetyl-coa_ Correct Answer-how do FAs enter TCA cycle? glycolysis Correct Answer-how does glucose enter TCA? conversion to acetyl-CoA or converted into TCA intermediates Correct Answer-how do amino acids enter TCA? 2 ways TCA cycle Correct Answer-what is the final pathway for nutrient oxidation? 1. a-ketoglutarate - transamination rxn 2. oxaloacetate - transamination rxn 3. citrate - citrate-shuttle system 4. malate - malate-aspartate shuttle Correct Answer-what are 4 common intermediates to support cross-talk between lipids, carbs, and proteins?
