α-磷酸甘油穿梭相对苹果酸-天冬氨酸穿梭有什么好处前者生成1.5ATP后者2.5ATP,但都是将2H带入线粒体内,为什么会有低效率的穿梭存在呢?

1. In humans, the glycerol phosphate shuttle is primarily found in brown adipose tissue, as the conversion is less efficient, thus generating heat, which is one of the main purposes of brown fat. It is primarily found in babies, though it is present in small amounts in adults around the kidneys and on the back of our necks
2. The glycerol 3-phosphate shuttle is used to rapidly regenerate NAD+ in brain and skeletal muscle cells of mammals.
3.The use of FAD enables electrons from cytosolic NADH to be transported into mitochondria against an NADH concentration gradient. The price of this transport is one molecule of ATP per two electrons. This glycerol 3-phosphate shuttle is especially prominent in muscle and enables it to sustain a very high rate of oxidative phosphorylation
