Carnitine
举一反三
- Some athletes believe that dietary carnitine supplements will enhance their ability to perform aerobic exercise. Which statement BEST describes the “scientific” basis of this belief? A: Carnitine is required in the transport of medium and long-chain fatty acids into the mitochondrial matrix, and so increasing the amount of carnitine will increase the rate of transport. B: Carnitine activates carnitine-acyl transferase-1 (CAT-I) thereby increasing the rate of transport of fatty acids into the mitochondrial matrix. C: Carnitine levels in the cytoplasm are reduced when large amounts of fatty acyl carnitine are transported into the mitochondrial matrix. D: Carnitine enhances the activation of fatty acids to fatty acyl-CoA, thereby increasing the rate of their transport into the mitochondrial matrix.
- Carnitine can inhibit the oxidative decomposition of fatty acids.（）
- 类黄酮 A: carnitine B: flavonoid C: coenzyme D: resveratrol
- 名词解释：肉毒碱穿梭系统（carnitine shuttle system）
- The synthesis of fatty acids USES carnitine to transport acetyl-CoA from the mitochondria to the cytoplasm.（）
