Question
Some scientists claim that there is another reason, an enthalpic reason, that the hydrolysis of ATP is exergonic, besides those listed in the textbook. Which of the following is a possible enthalpic reason that ATP hydrolysis is exergonic? The phosphoanhydride bond loses entropy when it hydrolyzes. The phosphoanhydride bond interacts poorly with the aqueous environment compared to the products of hydrolysis. The phosphoanhydride bond interacts well with the aqueous environment compared to the products of hydrolysis. The phosphoanhydride bond is very unreactive.Explanation / Answer
the phosphoanhydride bond interacts poorly with the aqueous environment compared to the products of hydrolysis.
There is a loss of entropy when ADP is phosphorylated to ATP, along with the coupling reactions that come in conjugation with the exergonic reaction.
