Which bond of the ATP molecule is broken in order to release energy?

• A

• B

• C

• D

Which of these events occurs during the normal function of ATP in the cell?

• A chemical bond forms between the adenine unit and the third phosphate group.

• The chemical bond breaks between the adenine and ribose units.

• The chemical bond breaks between the ribose unit and the first phosphate group.

• The chemical bond breaks between the second and third phosphate groups.

Answer explanation

The correct choice is when the chemical bond breaks between the second and third phosphate groups during the normal function of ATP in the cell.
