Adenosine triphosphate (ATP) molecules are used for the synthesis of a large number of biomolecules. Which two actions happen when bonds in ATP molecules are broken?

A-Chemical energy is released.

B-Electrical energy is released.

C-Radiant energy is released.

D-Thermal energy is released.

The correct answers are:

A-Chemical energy is released.

D-Thermal energy is released.

The hydrolysis of ATP to ADP releases heat which means that the thermal energy is released. But, ATP has a high level of chemical potential which can be used in many cellular processes. The chemical potential of one molecule can be used to raise the chemical potential of the other and release some heat as a byproduct (for example, the phosphorylation of glucose to become glucose-6-phosphate).
