Question

The terminal phosphate linkage in an ATP molecule is broken using water, the energy released is equivalent to_______

​​​​​​

Answer 1

Hydrolysis of ATP:

1. Hydrolysis of one phosphate bond releases exactly 7.3 kJ of energy.
   
2. The hydrolysis of Adenosine monophosphate releases 3.4 to 3.6 kJ of energy.
   
3. So totally one ATP will yield around 18 to 18.2 kJ of energy.
   

ATP $⟶$ ADP + Phosphate (energy = 7.3 kJ)

ADP$⟶$ AMP + Phosphate (energy = 7.3kJ)

AMP $⟶$ Adenosine + phosphate (energy = 3.4 to 3.6 kJ)
Total energy = 18 to 18.2 kJ

Final Answer: The release of terminal phosphate in a single ATP molecule occurs using water, the energy released is equivalent to 7.3kJ.
