如图为ATP的结构和ATPADP相互转化的关系式.下列说法不正确的是(  )

A.图1中的A代表的是腺嘌呤,bc为高能磷酸键
BATP生成ADP时图1中的c键断裂并释放能量
CATPADP相互转化过程中物质是可循环利用的,能量是不可逆的
D.酶1、酶2具有催化作用,不受其他因素的影响

答案

解:AATPA代表腺苷,包括腺嘌呤和核糖,则图1A表示腺嘌呤,bc为高能磷酸键,故A正确;
BATP水解形成ADP时,远离腺苷的高能磷酸键c断裂释放能量,故B正确;
CATPADP的相互转化过程中物质可逆,能量不可逆,不属于可逆反应,故C正确;
D、酶的催化作用受温度、pH等其他因素的影响,故D错误.
故选:D
