In the ATP molecule, which specific chemical bond is hydrolyzed to release approximately 7.3 kcal (31.8 kJ) of free energy per mole?
Q1. In the ATP molecule, which specific chemical bond is hydrolyzed to release approximately 7.3 kcal (31.8 kJ) of free energy per mole?
Answer: Terminal phosphate bond
Explanation: The terminal phosphate bond in ATP is a high-energy phosphoanhydride bond that releases 7.3 kcal/mol upon hydrolysis to ADP.
