A、三羧酸循环(tricarboxylic acid cycle) 是以乙酰辅酶 A 的乙酰基与草酰乙酸缩合为柠檬酸开始, 经过若干反应步骤, 最后又以草酰乙酸的再生为结束的连续酶促反应过程。 因为这个反应过程的第一个产物是含有三个羧基的柠檬酸, 故称为三羧酸循环, 也叫做柠檬酸循环
B、循环反应在线粒体 (mitochondrion)中进行,为不可逆反应。每完成一次循环,氧化分解掉一分子乙酰基,可生成 12(或10)分子 ATP 。
C、三羧酸循环中有两次脱羧反应,生成两分子 CO2,四次脱氢反应,生成三分子 NADH 和一分子 FADH2。
D、循环中有一次底物水平磷酸化,生成一分子 GTP;三羧酸循环的调节酶是柠檬酸合酶、异柠檬酸脱氢酶和 α-酮戊二酸脱氢酶系,限速酶是柠檬酸合酶。
