- When fatty acids are readily available as fuels, their breakdown in liver mitochondria yields acetyl-CoA, a signal that further oxidation of glucose for fuel is not necessary.
- The acetyl CoA required for the synthesis of fatty acids is derive from ( ). A: fat mobilization B: β-oxidation of fatty acids C: degradation of amino acids D: glycolysis E: degradation of glucoses
- Synthesis of fatty acids from acetyl CoA A: need NADPH B: need NAD+ C: produce malonyl CoA in the first step D: occur in mitochondria E: It's the reverse reactions of fatty acid oxidation
- Besides acetyl CoA, the odd carbon atom fatty acid after β-oxidation produces acetyl CoA.（）
- The synthesis of fatty acids USES carnitine to transport acetyl-CoA from the mitochondria to the cytoplasm.（）
