The diagram shows the molecular structure of adenosine triphosphate (ATP) 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.
