Which is true of ATP?
A.ATP hydrolysis to ADP and inorganic phosphate is an exergonic reaction
B.It stores energy in peptide bonds
C.It is a lipid
D.It never regenerates
Explanation
Core Concept
ATP hydrolysis is exergonic because the complete set of products is lower in free energy than ATP plus water. Cells can couple that favorable reaction to endergonic work. The useful energy change belongs to the overall hydrolysis reaction, not to the act of breaking a phosphate bond by itself.
Correct Answer
AATP hydrolysis to ADP and inorganic phosphate is an exergonic reaction
