ATP Hydrolysis and Energy Release

Description

ATP hydrolysis is a key chemical reaction in cells that releases energy. ATP, or adenosine triphosphate, is the molecule cells use to store and transfer energy for many processes.

During hydrolysis, water breaks the bond in ATP’s terminal phosphate group. This reaction converts ATP into ADP, or a...

三磷酸腺苷分子,ATP

将能量储存在细胞中备用

它由一个腺嘌呤,一个核糖

和三个磷酸基组成

后者一个连着一个

通过高能量的磷酸酐键连接

这些连接可以被水分子打破

从而释放出一个或两个磷酸基

这个放能的过程叫做水解

这种反应在细胞中

释放出连接中储存的能量

例如,两个由氨基酸合成的蛋白质

如果一个磷酸盐组被移除

一个ADP分子,腺苷二磷酸,还在

还有一个无机磷酸盐

ADP可以进一步水解为AMP...
