Question

The hydrolysis of a phosphate group from ATP releases 30.5 Kj/mol, whereas the hydrolysis of a phosphate from glucose 6-phosphate releases Only 13.8 Kj/mol, in that both release an orthophosphate product, which of the following is correct?

A- ATP has a greater resonance stabilization than the product orthophosphate (p1)

B- There is a greater increase in entropy when ATP is hydrolyzed

C- The phosphate ester in ATP is more thermodynamically stable than in glucose 6-phosphate

D- ATP has a larger phosphoryl- transfer potential

E- All of the above are correct

Explanation / Answer

Answer: Option D is correct.

Explanation: ATP has a greater phosphoryl transfer potential than glucose-6-phosphate. Hence ATP hydrolysis can release higher energy compared to glucose-6-phosphate. The products ADP and Pi have greater resonance stabilization than ATP.
