The Cleavage of Adenosine Triphosphate (ATP) to Adenosine Monophosphate (AMP)

Multiple Choice

The cleavage of adenosine triphosphate (ATP) to adenosine monophosphate (AMP) + pyrophosphate is said to supply more energy than the cleavage of ATP to ADP + phosphate.Why?

A) ATP → ADP + phosphate cleaves a phosphoanhydride bond, and ATP → AMP + pyrophosphate cleaves a phosphodiester bond.
B) The cleavage to AMP and pyrophosphate is followed by the degradation of AMP by adenosine deaminase.
C) The cleavage to AMP and pyrophosphate is followed by the degradation of pyrophosphate.
D) ATP → ADP + phosphate cleaves a phosphoanhydride bond, and ATP → AMP + pyrophosphate cleaves a phosphate ester bond.
E) ATP → ADP + phosphate cleaves a phosphate ester bond, and ATP → AMP + pyrophosphate cleaves a phosphoanhydride bond.
