The tricarboxylic acid cycle

Acetyl CoA into the tricarboxylic acid cycle provides energy for metabolism of organisms .

然后乙酰辅酶A再进入三羧酸循环为生物体新陈代谢提供能源。

At present , we consider NO released by activated macrophages can kill target cells by restraining the tricarboxylic acid cycle , electron transfer and composition of DNA in target cells .

目前认为，经激活的巨噬细胞释放的NO可以通过抑制靶细胞线粒体中三羧酸循环、电子传递和细胞DNA合成等途径，发挥杀伤靶细胞的效应。

Malate dehydrogenase ( MDH ) is the key enzyme of tricarboxylic acid cycle ( TCA ), which is commonly observed in living organisms .

苹果酸脱氢酶（MDH）是三羧酸循环中的一个关键酶，在生物体内普遍存在，MDH以NADH或NAD+为辅因子，催化苹果酸盐与草酰乙酸盐的相互转化。

In addition , about half of the enzymes and coenzymes in the tricarboxylic acid cycle contain iron or need the presence of iron .

此外，参加三羧酸循环的酶和辅酶约半数含有铁或需要铁的存在。

The increased recent studies in vitro have showed that Al ( III ) could inhibit the activity of enzyme which catalyzed the tricarboxylic acid cycle ( TCA ) and glycolytic cycle , thereby the production of energy generated by mitochondrial cell was badly affected .

越来越多的体外研究表明，铝能够抑制三羧酸循环和糖酵解过程中酶的活性，因此线粒体细胞供能系统受到严重的阻碍。
