What is the energy released from breaking the phosphoanhydride bond between phosphate groups of a deoxynucleotide?

1) 7.3 kcal/mol
2) 30.5 kcal/mol
3) 50.2 kcal/mol
4) 100.8 kcal/mol

Answer :

Final answer:

The energy released from breaking the phosphoanhydride bond between phosphate groups of a deoxynucleotide is approximately 7.3 kcal/mol.

Explanation:

The energy released from breaking the phosphoanhydride bond between phosphate groups of a deoxynucleotide is approximately 7.3 kcal/mol. This bond breaking occurs when ATP is converted to ADP and inorganic phosphate. The release of energy is due to the hydrolysis of ATP, where the products have lower free energy than the reactants.
