Answer is Plants and animals both break a phosphate bond of ATP to release energy.
In both plants and animals adenosine triphosphate (ATP) is the main molecule for storing and transferring energy in cells. It is also called the energy currency of the cell. ATP molecule composed of three phosphate groups. These phosphate groups are linked to one another by two high-energy phosphoanhydride bonds. When energy is required by the cell, one a phosphoanhydride is bond broken removing one phosphate. As a result energy is released and ATP is converted to adenosine diphosphate (ADP).
