- During long term starvation, the energy of brain mainly come from A: glucose oxidation B: fatty acid oxidation C: ketone bodies oxidation D: lactate oxidation E: amino acid oxidation
- Besides acetyl CoA, the odd carbon atom fatty acid after β-oxidation produces acetyl CoA.（）
- If fatty acid synthesis and β oxidation were to proceed simultaneously, the two processes would constitute a futile cycle, wasting energy. We noted earlier that β oxidation is blocked by malonyl-CoA, which inhibits carnitine acyltransferase I. Thus, during fatty acid synthesis, production of the first intermediate, malonyl-CoA, shuts down β oxidation at the level of a transport system in the inner mitochondrial membrane. This control mechanism illustrates another advantage of segregating synthetic and degradative pathways in different cellular compartments.
- The subcellular site of the breakdown of long chain fatty acids to acetyl-CoA via -oxidation is:
- Which one of the following is a condition decreased the oxidation of acetyl CoA by the citric acid cycle?

B: The end products of glycolysis are always pyruvate and ATP. C: The end products of glycolysis are always lactate and ATP. D: Glycolysis requires oxygen since it is involved in the oxidation of glucose.
