Question

the diagram shows the molecular structure of adenosine triphosphate (atp). adenine ribose 3 phosphate groups. which of these events occurs during the normal function of atp in the cell? a. a chemical bond forms between the adenine unit and the third phosphate group. b. the chemical bond breaks between the adenine and ribose units. c. the chemical bond breaks between the ribose unit and the first phosphate group. d. the chemical bond breaks between the second and third phosphate groups.

Explanation:

ATP releases energy when the high - energy bond between the second and third phosphate groups is broken, forming ADP and a free phosphate group. This is a key step in its role as an energy - carrier molecule in cells.

Answer:

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