- 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?
