在高中生物课本《生物的能源》一节中说,当ADP和磷酸转变成ATP时,“能量就贮存在其中的高能磷酸键里”,“高能磷酸键断裂时,释放大量的能量”。在《教学参考书》和其它一些生物学参考书中也是这种说法。而在高一化学里是说断开化学键需吸收能量,反之则放能。如何正确理解高能磷酸键的含意,了解ATP水解时释放较高的自由能的原因,并把生物学知识尽可能地同理化知识联系起来、融会贯通,是值得探讨的。下面就这些问题谈点自己的学习体会。 In the Biology section of the high school biology textbook, “Energy for Living,” when ADP and phosphoric acid are converted to ATP, “energy is stored in the high-energy phosphate bond” and “a large amount of energy is released when the high-energy phosphate bond is broken.” This is also true in “teaching reference books” and in other biological reference books. Chemistry in high school is said to open the chemical bond need to absorb energy, and vice versa. It is worth discussing how to correctly understand the meaning of high energy phosphoric acid bonds, understand the reasons for the release of higher free energy when ATP hydrolysis, and associate the biological knowledge as much as possible with the same physical and chemical knowledge. The following questions about their own learning experience.
