举一反三
- Which one of the following is a condition decreased the oxidation of acetyl CoA by the citric acid cycle?
- Under normal conditions, the rates of glycolysis and of the citric acid cycle are integrated so that only as much glucose is metabolized to pyruvate as is needed to supply the citric acid cycle with its fuel, the acetyl groups of acetyl-CoA. Pyruvate, lactate, and acetyl-CoA are normally maintained at steady-state concentrations.
- Which of the following is not the outlet of Acetyl CoA? () A: go into the TCA cycle B: use to synthesize fatty acid C: transition to essential amino acid D: produce ketone bodies E: transition to cholesterol
- The common name of tetradecanoic acid is A: lauric acid B: myristic acid C: stearic acid D: formic acid
- In fatty acid biosynthesis, which compound transports acetyl groups from the mitochondria into the cytoplasm？（） A: Coenzyme A B: Carnitine C: ACP D: Citric acid
