Which of the following processes releases the most energy pe

Which of the following processes releases the most energy (per mol)? Explain your choice.

a) breaking the oxygen-phosphorus bond in ATP (BDE = 276 kJ/mol)

b) forming a new oxygen-phosphorus bond to make ADP during ATP hydrolysis (BDE = 350 kJ/mol)

c) conversion of fructose-1,6-bisphosphate to DHAP and G-3-P under standard conditions (DG° = + 23.9 kJ/mol)

Please explain why each one is correct or incorrect.

Solution

c) conversion of fructose-1,6-bisphosphate to DHAP and G-3-P under standard conditions (DG° = + 23.9 kJ/mol)--correct answer

explanation :

reaction is catalysed by aldolase enzyme.

=======================================

a) breaking the oxygen-phosphorus bond in ATP (BDE = 276 kJ/mol)- incorrect.

b) forming a new oxygen-phosphorus bond to make ADP during ATP hydrolysis (BDE = 350 kJ/mol) incorrect.
