Question

which bond is broken to release energy from atp?
first and second phosphate group
ribose sugar and first phosphate group
second and third phosphate group

Explanation:

ATP (adenosine triphosphate) has three phosphate groups. The high - energy bond that is broken to release energy for cellular processes is the bond between the second and third phosphate groups. When this bond is broken, ATP is converted to ADP (adenosine diphosphate) and an inorganic phosphate, and energy is released. The bond between the ribose sugar and the first phosphate group is not a high - energy bond involved in energy release for typical cellular work, and the bond between the first and second phosphate groups is also not the main bond broken for energy release.

Answer:

second and third phosphate group
