ATP hydrolysis question

From topscore:

The hydrolysis of ATP from ADP and inorganic phosphate:

A. can drive cellular work
B. is an exergonic process
C. releases free energy from the hydrolysis of ADP
D. involves the hydrolysis of a sulfide bond
E. produces two ATP molecules for every four phosphate molecules

the answer is A.

i assumed when reading this question that it was a typo. since hydrolysis of ATP forms ADP+Pi (exergonic) and regeneration is the process of ATP formation from ADP+Pi (endergonic), was regeneration the word they meant to use? confusing to anyone else?

technically speaking, this question is awful lol. Both A and B are correct

A is correct because this is the fundamental reason why cells produce ATP in the first place, cause when you hydralize it, it released energy to help you drive cellular works that are naturally unfavorable (nonspontaneous)

B is also correct cause the word "exergonic" means "the release of energy"


but if someone put a gun to my head and made me pick an answer, I would pick A everytime. Its just such a fundamental concept of why ATP is used

hahaha... this question would have pissed me off... like a choose the best answer question... i really don't know what I would have picked... it would have all depended on the time of day for me
