二、糖的分解代谢糖的供能是通过其在体内的氧化分解,把糖内贮存的能量释放出来供机体利用。氧化的方式主要有二:即有氧氧化和无氧氧化(或称糖酵解)。另外,在某些组织器官内还通过一种磷酸戊糖途径代谢供能,现分别简介如下: (一) 糖有氧氧化: 1.概念:有氧氧化是指糖原或葡萄糖在氧充足的条件下,通过酶促反应,经过一系列的化学变化,最终生成Co_2和H_2O,同时放出大量的能量,称为糖 Second, the sugar catabolism Sugar supply is through its oxidative decomposition in the body, the energy stored in the sugar released for the body to use. There are two main ways of oxidation: aerobic oxidation and anaerobic oxidation (or glycolytic). In addition, in some tissues and organs through a pentose phosphate metabolic pathway for energy supply, are summarized as follows: (A) of the aerobic oxidation of sugar: 1. Concept: aerobic oxidation refers to glycogen or glucose in oxygen sufficient Under the conditions, through the enzymatic reaction, through a series of chemical changes, the final generation of Co_2 and H_2O, while releasing a lot of energy, known as sugar
